cmd/compile/internal/types: remove Markdcl/Pushdcl/Popdcl

Browse source 
Sym.Def used to be used for symbol resolution during the
old (pre-types2) typechecker. But since moving to types2-based IR
construction, we haven't really had a need for Sym.Def to ever refer
to anything but the package-scope definition, because types2 handles
symbol resolution for us.

This CL finally removes the Markdcl/Pushdcl/Popdcl functions that have
been a recurring source of issues in the past.
