[acpi] Begin consolidating acpi methods, add _OSC and _SEG

- Create wrappers for _BBN, _PSV, _CRT and _TMP
- Add _OSC and _SEG

The acpi_*_call wrappers are not fundamentally different than
the integer calls they replace, but standarize errors on
zx_status_t and start to centralize the ACPI method invocations.

Other methods will be moved as refactors happen.

Test: Tested on nuc and qemu for regressions, and verified _OSC
calls return values according to spec.
