  [WGSL] Implement compound assignment parsing and code gen
https://bugs.webkit.org/show_bug.cgi?id=255754
rdar://problem/108347694

Reviewed by Tadeu Zagallo.

Implement parsing and code gen for compound assignment statements (eg. "x +=
1"). Doesn't implement type checking, which will be implemented in a follow up patch.
