Than McIntosh 821420d6bb cmd/link/internal/loadpe: generalize handling of "__imp_*" syms
The existing PE file loader has a special case for the symbol
"__acrt_iob_func", whose hosting object file contains both an actual
definition and also a DLL import symbol "__imp___acrt_iob_func". The
normal way of handling __imp_XXX symbols is for the host object loader
to rename them to their intended target (e.g. "XXX") however if the
target is also defined locally, you get a duplicate definition.

This patch generalizes the def/import symbol detection to apply to all
symbols in the object file being loaded (not just a hard-coded set),
since it will be needed when reading things like crt2.o.

Updates #35006.
