  [WGSL] Initial plumbing for evaluating override expressions from the API
https://bugs.webkit.org/show_bug.cgi?id=262562
rdar://116414218

Reviewed by Mike Wyrzykowski.

The API needs to be able to evaluate override expressions for e.g. attributes and
override variable initializer expressions. This is first step in that direction,
which exposes a (currently very limited) function to evaluate expressions from the
API. This initial implementation, although very basic, should unblock some of the
samples that require resolving override variables in the workgroup_size attribute.
