This fixes two bugs and adds some enhancements to the handling of
characters and strings in objects being printed by the CM ObjectParser.
Bug fixes:
1. PrintOemID() currently attempts to print characters with "%C",
but the correct syntax is (lowercase) "%c". This bug results in
"CCCCCC" being printed instead of the actual ASCII characters.
2. PrintString() is being passed a pointer to data in objects, but in
some cases this data is the actual string to print and other cases
it is a pointer to the string to print. This adds a PrintStringPtr
function and uses the correct functions depending on the situation.
Enhancements:
1. Some objects contain ASCII characters, which are currently printed
as their hex values. This adds functions to print out ASCII
character fields as text rather than hex, and uses those functions in
several cases where the object data is defined to be ASCII.
2. The PrintOemID() function is replaced with the new identical but more
generecically-named PrintChar6() function.

The topology of a platform is represented in ACPI using the PPTT
table. It is possible to append information to CPUs/processor
containers using their associated AML nodes in a SSDT
table.
A platform might have multiple 'physical packages' (or top-level
nodes) in their PPTT topology representation. It can be assumed
from [1] that a 'physical packages' is always a 'top-level node',
and conversely.
The SSDT topology generator doesn't support having multiple top-level
nodes. The top-level node is also not generated in the SSDT topology
representation.
Add support to generate multiple top-level nodes in the SSDT topology
generator and generate an AML node for this top-level node. This will
allow to have matching PPTT and SSDT topology representations. Prior
to this patch, this top-level AML node was not generated.
Also factorize the flag checking in CheckProcNode() and add more
checks.
This patch takes inspiration from the discussion at:
- v1: https://edk2.groups.io/g/devel/message/99410
- v2: https://edk2.groups.io/g/devel/message/99615

ACPI 6.5, 5.2.30.1 Processor hierarchy node structure (Type 0):
- "Multiple trees may be described, covering for example multiple
packages. For the root of a tree, the parent pointer should be 0.""
- "Each valid processor must belong to exactly one package. That is,
the leaf must itself be a physical package or have an ancestor
marked as a physical package."
