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
implementation that uses O_TMPFILE to avoid having the temporary files
linked in the filesystem.
Refactor the existing tests to use the new ScopedTmpFile instead of
duplicating the same ScopedTestFile wrapper into each test.

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.

Fix more memory leaks, specifically for Module::Extern and

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.
