This patch consolidates ACPI OEM fields handling
by:
- Moving common code in PC and MICROVM to X86.
- Changes unnecessary dynamic memory allocation to static allocation
- Uses dedicated structure to keep values of fields instead of two
separate strings
- Adds helper macros to initialize the structure
v2:
- Move the setters/getters of OEM fields to X86MachineState to
remove duplication
- Change commit message to make it clear the second commit is
a re-factor
v3:
- Rebase "acpi: Consolidate the handling of OEM ID and OEM
Table ID fields to latest" to latest HEAD
- Dropped "acpi: Move setters/getters of oem fields to
X86MachineState" since it was accepted already

Introduces structure AcpiBuildOem to hold the value of OEM fields and
uses dedicated macros to initialize/set the values.
Unnecessary dynamically allocated OEM fields are re-factored to static
allocation.

we generally avoid names starting with __. No need for that

OK but ... why are these macros? Won't inline functions
work just as well with more type safety?
Also pls change names so they have a common prefix.
E.g. ACPI_BUILD_OEM_INIT, ACPI_BUILD_OEM_SET etc.

Unfortunately ACPI_BUILD_APPNAME8 is still used in build_header() in
aml-build.c, and to me it didn't look nice for one to have a define and
the other not, but if you prefer with only ACPI_BUILD_APPNAME8 as a
define, I can do the change.

Didn't know what was the attitude in this project to inlined functions
in headers and went with macros. I will change to inlined functions.
