[WGSL] Remove arena allocation
https://bugs.webkit.org/show_bug.cgi?id=292928
rdar://150858621
Reviewed by Mike Wyrzykowski.
Keep the lifetime tracking in the ASTBuilder, but allocate each node
individually
with system malloc instead of allocating arenas. We're currently seeing some
crashes
under the arena allocation that we can't find the root cause for, and we hope
that
by using system malloc instead it might help us identify the issue.
