Support Fat Mach-O Archive Libraries

[CouleeApps]

Universal archive libraries (.a extension) exist, but we currently do not parse them. They contain a Fat Mach-O header but each arch slice is actually an archive library, which is not a Mach-O. While we currently don't support archive libraries either (issue #2085), the Fat Mach-O loader still tries to parse these as Mach-O, shows Mach-O load options, and throws a bunch of errors in the process.

Expected behavior: Fat-Mach-O loader recognizes the slices are not Mach-O and does not try to create Mach-O views for them.

This appears to be resolved by the recent container transform system update which now handles Universal binaries. Opening a Universal archive file (e.g. /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib/libl.a) through the container browser no longer produces errors. The archive slices are recognized as Raw views and load as Mapped, which is reasonable behavior given that archive library support isn't yet implemented (#2085).

Recommend closing this ticket in favor of #2085.
