Initialize rows lazily (#15524)
For a 120x9001 terminal, a01500f reduced the private working set of
conhost by roughly 0.7MB, presumably due to tighter `ROW` packing, but
also increased it by 2.1MB due to the addition of the `_charOffsets`
array on each `ROW` instance. An option to fix this would be to only
allocate a `_charOffsets` if the first wide or complex Unicode glyph
is encountered. But on one hand this would be quite western-centric
and unfairly hurt most languages that exist and on another we can get
rid of the `_charOffsets` array entirely in the future by injecting
ZWNJs if a write begins with a combining glyph and just recount each
row from the start. That's still faster than fragmented memory.
This commit goes a different way and instead reduces the working
set of conhost after it launches from 7MB down to just 2MB,
by only committing ROWs when they're first used.
Finally, it adds a "scratchpad" row which can be used to build
more complex contents, for instance to horizontally scroll them.
## Validation Steps Performed
* Traditional resize
* Horizontal shrinking works ✅
* Vertical shrinking works ✅ and cursor stays in the viewport ✅
* Reflow works ✅
* Filling the buffer with ASCII works ✅ and no leaks ✅
* Filling the buffer with complex Unicode works ✅ and no leaks ✅
* `^[[3J` erases scrollback ✅
* Test `ScrollRows` with a positive delta ✅
* I don't know how to test `Reset`. ❔ Unit tests use it though
