  Log Message:
  -----------
  [WebAssembly] Allow inlining functions with different features

Allow inlining only when the Callee has a subset of the Caller's
features. In principle, we should be able to inline regardless of any
features because WebAssembly supports features at module granularity,
not function granularity, but without this restriction it would be
possible for a module to "forget" about features if all the functions
that used them were inlined.

Requested in PR46812.
