In addition to adding a parser for the universal binary format, this
also requires major reworks to handle files that contain different
DWARF information for different architectures, and how to pass the
architecture down to where it's needed.
Also fix dSYM handling: instead of assuming the name of the MachO file
corresponds exactly to the basename of the dSYM with the extension
stripped, just look for the single file within the
Contents/Resources/DWARF directory.
Also add `unrecognized` enum entries for DW_TAG, DW_AT, and DW_FORM
values that aren't handled.

Examples of the new line added to non-symbolic stack traces:
os: linux arch: x64 comp: yes sim: no
(Running on linux-x64c)
os: macos arch: arm64 comp: no sim: yes
(Running on mac-simarm64)
This CL also abstracts out the separate hardcoded strings across
the codebase for host and target OS and architecture into
definitions in platform/globals.h to ensure that they stay
in sync across different uses.

This is a reland of commit 08c13f173c
Fixes test failures on non-x64 architectures, both in the test
harness and due to DWARF5 line number program headers having a
non-backwards compatible format. (We generate DWARF2 in the
ELF snapshot writer, but the assembler used for assembly snapshots
may generate DWARF5.)

Now when -v/--verbose is used, we will also print call information
when those calls appear in stubs that do not correspond to Dart code.
The returned information contains the name of the stub (the name of
the static symbol in the ELF file generated for the stub) as well as
the offset of the frame PC within the stub payload.
This change also adds a flag --dump-debug-file-contents that
outputs the parsed information from the file passed via -d/--debug.
