These two identifiers were always very confusing. We're not filling and
injecting generators. We are filling SSDTs and injecting into the DSDT.
So drop the `_generator` suffix. Hopefully, this also makes ACPI look a

Sometimes coreboot needs to compile external code (e.g.
vboot_reference) using its own set of system header files.
When these headers don't line up with C Standard Library,
it causes problems.
Create stdio.h and stdarg.h header files. Relocate snprintf
into stdio.h and vsnprintf into stdarg.h from string.h.
Chain include these header files from string.h, since coreboot
doesn't care so much about the legacy POSIX location of these
functions.
Also move va_* definitions from vtxprintf.h into stdarg.h where
they belong (in POSIX). Just use our own definitions regardless
of GCC or LLVM.
Add string.h header to a few C files which should have had it
in the first place.

Replace DSDT ACPI code and DSDT injection with a SSDT only solution.
The current implementation shows some issues on current Linux, which
might be due to external ACPI objects, which are then injected into
DSDT or the fact that those objects only use 3 characters.
Replace all the DSDT code with an SSDT generator.
