OcMachoLib: Resolve indirect symbol ambiguity
...
Mach-O uses "indirect symbol" ambiguously. The first kind are "indirect
symbols" indicated by their type. They are located in the regular symbol
table, possibly outside the local, external and undefined ranges. Their
value is an index into the string table, which indicates the name of
another symbol they alias. We assume these to only be used by KPIs,
mostly as symbol aliases for deprecated symbol names.
The second kind is the "indirect symbol table", which is merely a flat
list of 32-bit indices into the symbol table.
When the handling code was written, the incorrect assumption was made
that the "indirect symbol table" is a range of "indirect symbols", much
like how local, external and undefined symbols are explicitly indexed.
However, this is not true and causes bugs in handling indirect symbols.
This patch drops this incorrect (and dangerous) assumption and strictly
separates the two concepts. As OpenCore does not inject KPIs, ignore
indirect symbols entirely.

OcMachoLib: Treat container Mach-O as reference file
...
As of macOS 13 Developer Beta 3, the Kernel Collection's inner kernel
references a segment that precedes itself. The current model is that
a Kernel Collection is a container format and the included files are
(mostly) separate. Hence, this was treated as an out-of-bounds issue.
Kernel Collections apparently are rather an unconventional composite
format, where the sub-files are still part of the whole. Redesign
OcMachoLib to treat the Kernel Collection as the reference file.
Patches still use only the inner file, while parsing considers the
whole file.
