PC port: full compile + link milestone (ge007.x86_64.exe builds clean)

All ~235 translation units now compile and the target links under MSYS2
GCC 16 + CMake/Ninja (ninja ge007 -k 0: 236/236, zero errors). N64 build
untouched; every src/ change is -DPORT-gated.

Portability fixes (findings D7-D17 in docs/PCPortResearch.md section 11):
- AI X-macro system: SWITCH() call sites activated to the author's
  hand-written byte-identical references under PORT; port/shim/
  bondaicommands.h + bondconstants.h + CPPLib.h re-emit the IDO paste
  tricks (isSubroutine, file-record macros, generated CALL) GCC-clean.
- 64-bit pointer-in-word initializers: monAnim jump targets now go
  through an index table resolved by the interpreter (chrai.h/propobj.c);
  UsetuplenZ.c credits pointer PORT-gated to 0.
- IDO printf engine compiled for PC (xprintf/xlitob/xldtob) with a
  shadow xstdio.h resolving the _Printf prototype clash.
- Host-libc gaps stubbed in port/: bcopy/bzero, __libm_qnan_f,
  tlbmanage*, g_ViXScales/YScales; chrObjRandom PRNG ported from .s.

Asset data strategy (D16): single-file assets compiled for real
(animation tables, fonts, textures, rareware logo); obseg per-file .c
excluded (colliding file-local globals the N64 build isolates via
per-ELF linking); 758 ROM-derived table symbols + ramrom_* + segment
markers stubbed in port/src/assetstubs.c / n64stubs.c.

fast3d is a no-op placeholder (port/src/gfxstub.c) until Phase 2 brings
in the real software RSP. Binary not yet runnable end-to-end: ROM
loading in romdata.c is still a TODO.
