[tvOS 16] Support building WebKit

https://bugs.webkit.org/show_bug.cgi?id=245095

Reviewed by Jonathan Bedard, Kimmo Kinnunen and Alex Christensen.

* Source/WebCore/PAL/pal/spi/cocoa/MetalSPI.h: The use site for
  MTLSharedTextureHandle is behind a !PLATFORM(IOS_FAMILY_SIMULATOR)
  block, but this SPI declaration was not.

* Source/WebKit/Scripts/webkit/messages.py: Move
  RemoteMediaSourceIdentifier, RemoteSourceBufferIdentifier,
  XRDeviceIdentifier to types_that_cannot_be_forward_declared. These
  symbols are not always available (in this case when building tvOS), so
  they cannot be generated as part of IPC::serializedIdentifiers.

* Source/WebKit/Scripts/webkit/tests/MessageArgumentDescriptions.cpp:
(IPC::serializedIdentifiers): Regenerated.
