Cherry Mui e924ea03cc cmd/link: disable DWARF by default in c-shared mode on darwin
Currently, linking a Go c-shared object with C code using Apple's
new linker, it fails with

% cc a.c go.so
ld: segment '__DWARF' filesize exceeds vmsize in 'go.so'

Apple's new linker has more checks for unmapped segments. It is
very hard to make it accept a Mach-O shared object with an
additional DWARF segment.

We may want to stop combinding DWARF into the shared object (see
also #62577). For now, disable DWARF by default in c-shared mode
on darwin. (One can still enable it with -ldflags=-w=0, which will
contain DWARF, but it will need the old C linker to link against
with.)

For #61229.
