Support v2 of 'main bin spec' Mach-O LC_NOTE in corefiles

Version 2 of 'main bin spec' LC_NOTE allows for the specification
of a slide of where the binary is loaded in the corefile virtual
address space. It also adds a (currently unused) platform field
for the main binary.

Some corefile creators will only have a UUID and an offset to be
applied to the binary.

Changed TestFirmwareCorefiles.py to test this new form of
'main bin spec' with a slide, and also to run on both x86_64
and arm64 macOS systems.

Handle all standalone combinations of LC_NOTEs w/ & w/o addr & uuid

Fill out ProcessMachCore::DoLoadCore to handle LC_NOTE hints with
a UUID or with a UUID+address, and load the binary at the specified
offset correctly. Add tests for all four combinations. Change
DynamicLoaderStatic to not re-set a Section's load address in the
Target if it's already been specified.

Add support for firmware/standalone LC_NOTE "main bin spec" corefiles

When a Mach-O corefile has an LC_NOTE "main bin spec" for a
standalone binary / firmware, with only a UUID and no load
address, try to locate the binary and dSYM by UUID and if
found, load it at offset 0 for the user.

Add a test case that tests a firmware/standalone corefile
with both the "kern ver str" and "main bin spec" LC_NOTEs.
