Issue 39002: Breakpad DWARF parser: Move DWARF parser to platform-independent directory.

Move the DWARF parser, and the functioninfo.cc DWARF consumer, from
src/common/mac/dwarf to src/commmon/dwarf, so that it can be shared
between the Mac and Linux dumpers.

Fix up #include directives, multiple inclusion protection macros, and
Xcode build files.
