This fixes a problem where if you press "Shift" and then "A", then release "Shift" and then "a", then the "A" key will be "stuck" on because the logical key for the key down message is different (capital "A") from the logical key for the key up message (lowercase "a").

This PR changes the pressed keys logic so that it uses the physical key to add/remove keys from the list of pressed keys, but keeps the associated logical key.

This does mean that after the "Shift" key goes up, the pressed keys contains a capital "A" and it doesn't switch to be a lowercase "a", but there isn't currently any mechanism we can use to do that remapping. This is far less surprising than the current behavior, but is still not quite correct.

I fixed the event simulation code to take a physicalKey so that it could be matched with the logical key, but the event simulation code isn't up to the task, since it can only simulate keys that appear in the key maps. The new platform key event design should fix that (added TODOs).

The next engine roll will introduce --lazy-async-stacks, which affects the
contents of stack traces.  This updates test expectations to match both the
old and new stack trace formats.

This reverts commit 0b5667ac.

With --lazy-async-stacks the stack output has changed slightly so updating the expect files to match.

This is a follow-up to https://github.com/flutter/flutter/pull/51047 as a preparation for the next engine roll which will start enabling --lazy-async-stacks in JIT mode.

* [Web] Add Material Card Infinite Scroll benchmark

Adds a benchmark that makes an infinite list of Material cards
and scrolls it. This benchmark exercises more heavyweight rendering
like shadows and clipping and paths.

This PR is a follow up of https://github.com/flutter/flutter/pull/42640
Some changes of that PR includes redundant changes using FlutterError.fromParts constructor even though it's not necessary.

Some minor changes are:

- Remove one unnecessary todo
- Fix indent consistencies

This reverts commit 0a623e87.

Weaken stack-trace based tests to allow auto-roll of new engine which will change the format (#51047)

Follow-up PR will restore those tests with new expectations:
