Updates minidump_dump to print out any Crashpad annotation objects that
are in a minidump. If an annotation contains a string value, it will be
printed out as such, otherwise it will be printed out as hex bytes.

This change removes ScopedTmpFile from DisassemblerObjdump, and
replaces it with the use of the implementation in linux/common.
It also switches to using ScopedPipe to read the output from objdump,
and directly execing objdump instead of using system.

This replaces the existing AutoTestFile implementation with a simpler

This checks in an edited version of a script that has been used by the
Chrome Mac team for this purpose. It expects to reside in the same
place as `dump_syms`, `dsc_extractor`[0], `symupload` and `upload_system_symbols` binaries.
When called, it will:
- Locate and extract any dyld_shared_caches found on the system
- Dump the above
- Dump any remaining uncached system libraries
- Write the results to a directory passed as an argument
- Provide (but not call) an `upload_system_symbols` invocation
to upload the results

On macOS 13 x86_64 machines, NXFindBestFatArch does not correctly find
arm64e slices. This is filed as FB11955188.
I was hoping manually masking the subtype with CPU_SUBTYPE_MASK would
be sufficient to work around but no luck. So let's just fall through
to doing an exact* match if NXFindBestFatArch fails.
* "Exact" meaning with CPU_SUBTYPE_MASK now masked off. But
libmacho/arch.c calls that exact too, so I'm just going to go with it.

To fix this, and to prevent issues like the one fixed by

in the future, switched to proper use of std::unique_ptr for Module's
Extern and StackFrameEntry functions. These should enforce ownership
correctly and make the ownership flow much more visible and clear.
