LOG: [lldb] Add armv7a and armv8a ArchSpecs (#106433)

armv7a and armv8a are common names for the application subarch for arm.

These names in particular are used in ChromeOS, Android, and a few other
known applications. In ChromeOS, we encountered a bug where armv7a arch
was not recognised and segfaulted when starting an executable on an
arm32 device.
