  [WGSL] Add support for f16
https://bugs.webkit.org/show_bug.cgi?id=265024
rdar://118561000

Reviewed by Mike Wyrzykowski.

Add support for f16 values and operations. Tests will be included in a follow-up
patch, as I ended up rewriting a lot of the tests, but this was also tested against
the CTS and passes all of the f16 binary expression tests.
