Update stack limit in ASan builds (#778) 
Otherwise recursive calls keep going until they trip ASan checks.

Remove the `__ASAN__` and `__UBSAN__` defines; no longer necessary.

Remove `globalThis.__running_with_sanitizer__` from qjs; likewise.

53b641d4b3 Fixes timezone bias on Windows 
`GetTimeZoneInformation`returns the bias in minutes already, so no need to adjust it.

Also handle the return code since it determines if the time zone is in the daylight saving range.

Simplify close_lexical_var (#726) 
Its implementation was borderline wrong: calling it with is_arg=TRUE
segfaults because it looks up the var ref index in the wrong array.

Fortunately, there is only one caller and it only passes FALSE.

Fix FinalizationRegistry refcounting bug (#656) 
Introduced in commit 61c8fe6 from last month that moved the callback
into the job queue:

1. It leaked `fre->held_val` when no job was enqueued

2. It fumbled the reference count when enqueuing; JS_EnqueueJob already
   takes care of incrementing and decrementing it

Reverts commit 0a70623 from earlier today because that didn't turn out
to be a complete fix.

Move "no more objects" assert to right place (#649)

Add resizable ArrayBuffers (#646) 
This commit implements resizable ArrayBuffers - RABs for short - and
extends typed arrays (TAs) to support fixed-length and length-tracking
modes.

SharedArrayBuffers (SABs) also support the maxByteLength option now but
I cheated and allocate all memory upfront because atomically resizing
memory allocations is hard and this commit is already big and complex.

The lion's share is updating all the TA prototype methods to deal with
RABs resizing underneath them. Method arguments can be arbitrary objects
with arbitrary .valueOf methods and arbitrary side effects, like...
resizing the RAB we're currently operating on.
