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.

* The page-routing logic is becoming too much complicated to stay as an inner function. Move it to its own class, and add some logic to workaround a limitation of playwright which just hangs if a Python exception is raised inside it
* no need to use a hash, we can use the url as the key
* re-implement the retry logic. The old @retry decorator was nice but a bit too over-engineered and most importantly failed silently in case of exceptions. This new approach is less powerful but since we want to retry only two times, simple is better than complex -- and in case of exception, the exception is actually raised
* improve logging

This is a follow-up of PR #806 and it's a big step forward towards solving issue #763.
The basic idea is that at this stage I want to streamline the execution logic
and make it as linear and easy to read/understand as possible. The diff is
relatively big, but for the most part is just "shuffling code around".
Svelte stores:
the idea is to eventually kill of them, so that we can remove the dependency
on svelte but also to avoid relying on so much global state, which makes
things more complicated and error-prone (e.g., we have several issues related
to using runtime when it's not ready yet).
I killed addInitializer, addPostInitializer and the corresponding svelte
stores tada. They are no longer needed since the relevant code is called
directly from main.ts.
I started to kill the usage of the runtimeLoaded svelte store: instead of
relying on a global variable, I want to arrive at the point in which the
runtime is passed as a parameter in all places where it's needed: pyscript.ts
is now free of global state, but I couldn't kill it yet because it's used
heavily by base.ts and pyrepl.ts. I will do it in another PR.
Other misc changes:
I added sanity checks (and corresponding tests!) which complain if you specify
0 or multiple runtimes. Currently we support having one and only one, so there
is no point to pretend otherwise
I modified the messages displayed by the loader, to be more informative from
the user point of view.
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 :).

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
