2aa6d7636c LibWeb: Invalidate sheet owners after mutating cssText of its rules 
This fixes one source of flakiness on WPT (of many) where we wouldn't
recompute style after programmatically altering the contents of a style
sheet, but instead had to wait for something else to cause invalidation.

6507d23e29 LibWeb: Save ScrollState snapshot in DisplayList to avoid race condition 
With this change we save a copy of of scroll state at the time of
recording a display list, instead of actual ScrollState pointer that
could be modifed by the main thread while display list is beings
rasterized on the rendering thread, which leads to a frame painted with
inconsistent scroll state.

Fixes https://github.com/LadybirdBrowser/ladybird/issues/4288

0b23717bc9 LibWeb/WebDriver: Use WebIDL promise AOs to execute async scripts 
This removes the use of `spin_event_loop_until` when waiting for async
script results.

8b7bbc81e3 LibWeb/WebDriver: Execute script bodies in a promise-calling manner 
This is a bit of a peculiarity with the synchronous script executor. We
must wrap the script result in a promise.

promise.py failures. This comment is to explain why.

eb0a51faf0 LibWeb: Implement ReadableStreamPipeTo according to spec 
Our existing implementation of stream piping was extremely ad-hoc. It
did nothing to handle closed/errored streams, and did not read from or
write to streams in a way required by the spec.

This new implementation uses a custom JS::Cell to drive the read/write
loop.

4010c4643a LibWeb: Support removing callbacks from AbortSignal 
This will be needed by Streams. To support this, we now store callbacks
in a hash table, keyed by an ID. Callers may use that ID to remove the
callback at a later point.

e9a7694cdb LibWeb: Prefer react_to_promise over upon_fulfillment + upon_rejection 
While debugging a spec-compliant implementation of ReadableStreamPipeTo,
I spent a lot of time inspecting promise internals. This is much less
noisy if we halve the number of temporary promises.

3033929bb6 LibWeb: Pass abort signal as its concrete type to ReadableStreamPipeTo

ab43c3be23 LibWeb: Store WritableStream's strategy high water mark as a double 
It is received from user JS as a double and is only used as a double in
all subsequent calculations. This bug would cause UBSAN errors in an
upcoming imported WPT test, which passes Infinity as the HWM.

Note there is an equivalent HWM for ReadableStream, which already stores
the value as a double.

8257788a20 LibWeb: Ignore negative margins for margin box rect 
Negative margins are processed through the `offset` in layout state, and
should not contribute to the margin box' rect's size or position.

938b1e91fe LibJS: Inline the fast path of Value::to_i32() and simplify to_u32() 
The fast path of to_i32() can be neatly inlined everywhere, and we still
have to_i32_slow_case() for non-trivial conversions.

For to_u32(), it really can just be implemented as a static cast to i32!
