[WGSL] Add support for address-of and indirection operators
https://bugs.webkit.org/show_bug.cgi?id=261833
<rdar://problem/115795658>
Reviewed by Dan Glastonbury.
Add the type declarations for address-of (&x, spec[1]) and indirection (*x,
spec[2])
operators. This required introducing AbstractReference and AbstractPointer to
the
overload resolution algorithm and exposing them to the ruby DSL, as well as
exposing
address space and access mode, which was done by generalizing NumericVariables
to
use the underlying enum type.
