44896b1680 acpi: move entities to the entity pkg, export them and add missing entities 
This commit moves the AML entity definitions into the entity package and
makes them exportable so we can reference them from other packages.

In addition, the commit adds some missing entity structs that were
previously treated as generic entities (e.g. Processor, PowerResource
and ThermalZone).

Finally, this commit cleans the definitions and adds missing struct
attributes for the various field types (Field, IndexField, BankField)

692155b44b acpi: refine post-parse entity processing rules 
This commit updates the post-parse step so that:
- the visitor not longer recurses into method bodies. Since code inside
  methods may potentially generate dynamic/scoped entities or even use
  conditional invocations (if CondRefOf(X) { X(...) }), symbol resolution
  will be deferred to the AML interpreter.
- parent-child relationships between entities are checked and updated if
  not properly specified

70c798f40a acpi: add pre-process step to capture arg counts for all function decls 
Since the ACPI standard allows forward function declarations this step
is required so we can properly parse the argument list for function
invocations. Contrary to other AML entities, method invocations do not
include any sort of pkgLength information so unless we track the
expected argument count for each function, our parser will not be able
to figure out where the argument list ends.
