  Log Message:
  -----------
  [WebAssembly][MC] Avoid the need for .size directives for functions

Warn if `.size` is specified for a function symbol.  The size of a
function symbol is determined solely by its content.

I noticed this simplification was possible while debugging #57427, but
this change doesn't fix that specific issue.
