The current code only allows chunk_calloc() callers to tell whether they
want zeroed memory or not, but some might be okay either way, assuming
they act accordingly afterwards. So move the zeroing out of chunk_alloc.
Many functions in the mozjemalloc codebase like to return the opposite
boolean one would tend to expect. Pages_purge is one of them, and this
reverses the logic to match expectations.
Also make it static.
blob URIs are sent through unfiltered and data URIs are hashed in
the same way as Chrome does.
Also, we used to bail on the first invalid URL we encountered. We now
keep going, checking the other URLs in the chain and eventually doing
the remote lookup.

When we turn on the pref security.data_uri.unique_opaque_origin to make
data URI is unique origin, the following tests will fail because now
data document is treated as cross origin, so we replace data URIs with
seperate files, hence it will still in the same origin.
It turns out that not recycling some kinds of chunk can lead to the
recycle queue being starved in some scenarios. When that happens, we end
up mmap()ing new memory, but that turns out to be significantly slower.
So instead of not recycling huge chunks, we force-clean them, before
madvising so that the pages can still be reclaimed in case of memory
pressure.

~AzureState is expensive, especially in GlyphBufferAzure::Flush, which is a high
fan-in function.

This allows us to reuse the minimum bound guards on the pref values in other
places that want to use the prefs.

<!-- Please describe your changes on the following line: -->
This is the final PR to get basic paint worklet support. It adds support for paint worklet properties (https://drafts.css-houdini.org/css-paint-api/#paint-definition-input-properties). When a paint worklet is registered, it specifies a list of CSS properties, and is provided with their computed values when it is invoked.
This is a dependent PR:
* "Implemented paint worklets invoking worklet scripts" is #17239.
* "Implemented paint worklets rendering contexts" is #17326.
There should be tests added for this, hopefully the existing wpt houdini tests.

This avoids MozStackWalk(), which has become unusably slow on Mac due to
changes in libunwind, and gets us back to decent speed.
The code for getting the frame pointer and stack end was copied from the Gecko
Profiler, which also uses FramePointerStackWalk() on Mac.

This gives us performance wins in sevaral areas:
- Creating a structured clone blob of storage data directly from the source
compartment allows us to avoid X-ray and JSON serialization overhead when
storing new values.
- Storing the intermediate StructuredCloneBlob, rather than JSON values,
in-memory saves us additional JSON and structured clone overhead when
passing the values to listeners and API callers, and saves us a fair amount
of memory to boot.
- Serializing storage values before sending them over a message manager allows
us to deserialize them directly into an extension scope on the other side,
saving us a lot of additional structured clone overhead and intermediate
garbage generation.
- Using JSONFile.jsm for storage lets us consolidate multiple storage file
write operations, rather than performing a separate JSON serialization for
each individual storage write.
- Additionally, this paves the way for us to transition to IndexedDB as a
storage backend, with full support for arbitrary structured-clone-compatible
data structures.
