Adrian Perez de Castro 917f05975f package/wpewebkit: bump to version 2.38.0 
Update to a new major release which brings in improvements and a few
new features. Release notes:

  https://wpewebkit.org/release/wpewebkit-2.38.0.html

This release also includes security fixes for CVE-2022-32886,
CVE-2022-32891, and CVE-2022-32912. Accompanying security advisory:

  https://wpewebkit.org/security/WSA-2022-0009.html

Both building documentation and support for gobject-introspection have
been added in this release. Version 2.38.0 also introduces a new WebRTC
implementation based on GstWebRTC. Options for them are explicitly left
disabled to keep the configuration as it was, and may be enabled in
follow-up patches. Lastly, the SILENCE_CROSS_COMPILATION_NOTICES option
removed because it no longer exists.

The patch that fixes the build on 32-bit ARM targets is also updated
for the 2.38 release series.

Subject: [PATCH] FELightningNEON.cpp fails to build, NEON fast path seems
unused https://bugs.webkit.org/show_bug.cgi?id=241182
Reviewed by NOBODY (OOPS!).
Move the NEON fast path for the SVG lighting filter effects into
FELightingSoftwareApplier, and arrange to actually use them by
forwarding calls to applyPlatformGeneric() into applyPlatformNeon().
Some changes were needed to adapt platformApplyNeon() to the current
state of filters after r286140. This was not detected because the code
bitrotted due to it being guarded with CPU(ARM_TRADITIONAL), which does
not get used much these days: CPU(ARM_THUMB2) is more common. It should
be possible to use the NEON fast paths also in Thumb mode, but that is
left for a follow-up fix.
