  Log Message:
  -----------
  [llvm-readobj] Display Mach-O CPU capability bits (#221617)

The Mach-O file header output masks the capability bits out of
`cpusubtype`
without printing them separately, so this information is missing from
the
output.

Add a `CpuCapabilities` field to print the high byte in hexadecimal,
matching the numeric representation used by `llvm-objdump`.

Fixes #80198.

description).
