Add no-inline IR annotation, and passes to set it based on function name (#6146)

Any function can now be annotated as not to be inlined fully (normally) or not to be
inlined partially. In the future we'll want to read those annotations from the proposed
wasm metadata section on code hints, and from wat text as well, but for now add
trivial passes that set those fields based on function name wildcards, e.g.:

--no-inline=*leave-alone* --inlining

That will not inline any function whose name contains "leave-alone" in the name.

--no-inline disables all inlining (full or partial) while --no-full-inline and
--no-partial-inline affect only full or partial inlining.
