Store SHA-256 hash of wire bytes for WASM V8 Code Cache

This CL stores and validates SHA-256 hash of wire bytes
in WASM V8 Code Cache to prevent mismatches between
wire bytes and code cache metadata.

When hitting code cache, this CL calculates the hash
while streaming wire bytes, and
invalidates the code cache metadata on hash mismatch,
by setting `can_use_compiled_module` to `false`
in `WasmStreaming::Finish()`.

The cached metadata is passed to V8 by
`SetCompiledModuleBytes()` when the first bytes of
the wire bytes are received, but this only triggers
suppressiong of streaming compilation and the
content of the cached metadata is not used until
`WasmStreaming::Finish(true)` is called later.

This CL also adds tracing events to measure hashing overhead
and observe cache rejection by hash mismatch.

This CL depends on V8 side CL:
