f9194cc833 Refactor how py-script are executed, kill scriptQueue store, introduce pyExec (#881)
Yet another refactoring to untangle the old mess.
Highlights:

base.ts, pyscript.ts and pyrepl.ts were a tangled mess of code, in which each of them interacted with the others in non-obvious ways. Now PyScript is no longer a subclass of BaseEvalElement and it is much simpler. I removed code for handling the attributes std-out and std-err because they are no longer needed with the new display() logic.

The logic for executing python code is now in pyexec.ts: so we are decoupling the process of "finding" the python code (handled by the py-script web component) and the logic to actually execute it. This has many advantages, including the fact that it will be more easily usable by other components (e.g. pyrepl). Also, note that it's called pyexec and not pyeval: in the vast majority of cases in Python you have statements to execute, and almost never expressions to evaluate.

I killed the last remaining global store, scriptQueue tada. As a bonus effect, now we automatically do the correct thing when a <py-script> tag is dynamically added to the DOM (I added a test for it). I did not remove svelte from packages.json, because I don't fully understand the implications: there are various options which mention svelte in rollup.js and tsconfig.json, so it's probably better to kill it in its own PR.

pyexec.ts is also responsible of handling the default target for display() and correct handling/visualization of exceptions. I fixed/improved/added display/output tests in the process.
I also found a problem though, see issue #878, so I improved the test and marked it as xfail.

I removed BaseEvalElement as the superclass of most components. Now the only class which inherits from it is PyRepl. In a follow-up PR, I plan to merge them into a single class and do more cleanup.

During the refactoring, I killed guidGenerator: now instead of generating random py-* IDs which are very hard to read for humans, we generated py-internal-X IDs, where X is 0, 1, 2, 3, etc. This makes writing tests and debugging much easier.

I improved a lot our test machinery: it turns out that PR #829 broke the ability to use/view sourcemaps inside the playwright browser (at least on my machine).
For some reason chromium is unable to find sourcemaps if you use playwrights internal routing. So I reintroduced the http_server fixture which was removed by that PR, and added a pytest option --no-fake-server to use it instead, useful for debugging. By default we are still using the fakeserver though (which is faster and parallelizable).

Similarly, I added --dev which implies --headed and also automatically open chrome dev tools.

beb3aa1574 kill stores.runtimeLoaded and many other stores (#850)
As the title stays, the main goal of the branch is to kill the infamous runtimeLoaded global store and all the complications, problems and bugs caused by the fact that in many places we needed to ensure/wait that the global runtime was properly set before being able to execute code.

The core idea is that runtime is never a global object and that it's passed around explicitly, which means that when a function receives it, it is guaranteed to be initialized&ready.

This caused a bit of complications in pybutton.ts, pyinputbox.ts and pyrepl.ts, because they indirectly want to call runtime.run from connectedCallback, which is the only place where we cannot explicitly pass the runtime because it's automatically called by the browser.
But also, it is also a sign of a bad design, because it were entirely possible that connectedCallback was called before the runtime was ready, which probably caused many bugs, see e.g. #673 and #747.

The solution to is use dependency injection and create the class later on: so instead of having a global PyButton class which relies on a global runtime (whose state is uncertain) we have a make_PyButton function which takes a runtime and make a PyButton class which is tied to that specific runtime (whose state is certainly ready, because we call make_PyButton only when we know that the runtime is ready).
Similar for PyInputBox and PyRepl.

Other highlights: thanks to this, I could kill the also infamous runAfterRuntimeInitialized and a couple of smelly lines which used setTimeout to "wait" for the runtime.

While I was at it, I also called a lot of other stores which were completely unused and where probably leftovers from a past universe.

c75f885cb4 Refactor py-config and the general initialization logic of the page (#806)
This PR is the first step to improve and rationalize the life-cycle of a pyscript app along the lines of what I described in #763 .
It is not a complete solution, more PRs will follow.
Highlights:

- py-config is no longer a web component: the old code relied on PyConfig.connectedCallback to do some logic, but then if no <py-config> tag was present, we had to introduce a dummy one with the sole goal of activating the callback. Now the logic is much more linear.

- the new pyconfig.ts only contains the code which is needed to parse the config; I also moved some relevant code from utils.ts because it didn't really belong to it

- the old PyConfig class did much more than dealing with the config: in particular, it contained the code to initialize the env and the runtime. Now this logic has been moved directly into main.ts, inside the new PyScriptApp class. I plan to refactor the initialization code in further PRs

- the current code relies too much on global state and global variables, they are everywhere. This PR is a first step to solve the problem by introducing a PyScriptApp class, which will hold all the mutable state of the page. Currently only config is stored there, but eventually I will migrate more state to it, until we will have only one global singleton, globalApp

- thanks to what I described above, I could kill the appConfig svelte store: one less store to kill :).

f3157b377f Improve JS logging (#743)
This PR tries to improve and rationalize what we log. Key points:
- introduce `logger.ts`: each file/component is encouraged to use the logger instead of writing directly to `console.*`
    * the logger automatically prepend a prefix like `[py-config]`, `[py-env]` which make it easier to understand where a certain message is printed from
    * it provide a central place where to add more features in the future. E.g., I can imagine having a config setting to completely silence the logs (not implemented yet)
- use the new loggers everywhere
- write to `.info()` instead of `.log()`. The idea is to keep `console.log` free, so that for the users it's easier to tell apart their own messages and the pyscript ones
- generally improve what we log. This is an endless exercise, but I tried to print more things which are useful to understand what's going on and in which order the various things are executed, and remove prints which were clearly debugging leftovers
