Reviewed by Andy Estes and Jean-Yves Avenard.

We update the project to include asm and .S files.
We exclude them for non arm64/arm64e builds.
We update Source/WebCore/PAL/ThirdParty/dav1d/config.h to enable ASM for arm64.
We add Source/WebCore/PAL/ThirdParty/dav1d/config folder from upstream repo as 
it is useful to update Source/WebCore/PAL/ThirdParty/dav1d/config.h.

Covered by existing tests.
