Michael Pratt 0fd6ae548f cmd/compile: escape package path for PGO symbol matching
Symbol names in the final executable apply escaping to the final
component of a package path (main in example.com becomes
example%2ecom.main).

ir.PkgFuncName does not perform this escaping, meaning we'd fail to
match functions that are escaped in the profile.

Add ir.LinkFuncName which does perform escaping and use it for PGO.

Fixes #59887.
