crt: build CRTDLL / libcntpr / libc / libcmt / INT64 from source

Imports CRT32 + CRT32NT + FP32 + FP32NT + CRTLIB from NT 3.5 PRIVATE/
plus eight long-long ASM helpers (LL{DIV,MUL,REM,SHL,SHR} + ULL{DIV,
REM,SHR}) from MSVC 2.2's CRTSRC/HELPER/I386.  PUBLIC/SDK/LIB/I386
now ships CRTDLL.{DLL,LIB}, LIBCNTPR.LIB, LIBC.LIB, LIBCMT.LIB,
EXSUP.LIB, INT64.LIB built from in-tree source rather than the
prebuilt blobs that landed with the original repo import.  NT 3.5's
dev-host orchestration scripts (BUILDCRT.CMD / BUILDALL.CMD /
GHOST*.CMD / etc.) are dropped — build.lua drives the chain now.

Three non-obvious fixes were load-bearing for the chain landing green:

  * Variant share.  Stock NT 3.5 kept four sibling trees (crt32st,
    crt32, crt32dll, crt32nt) so each variant owned its own obj/.
    Our single-tree remap silently re-archived the FIRST variant's
    .obj into every subsequent libc<suffix>.lib (CRTDLL.LIB link
    failed with ~40 unresolved externals on _environ_dll /
    _initterm / _HUGE_dll).  build_crt_variant now drops a
    .crt-variant stamp per subdir and wipes obj/ on mismatch.

  * ML debug info.  386_ADBGFLAGS=/Zi sits behind !IFDEF NTLEGO in
    I386MK.INC, and NTLEGO is unconditionally !UNDEFed whenever
    NTDEBUG is set (MAKEFILE.DEF:755).  Under our NTDEBUG=ntsdnodbg
    --syms path every .asm landed .text-only — no .debug$S, so
    splitsym extracted nothing and ASM execution coverage couldn't
    be attributed.  run_nmake now forces 386_ADBGFLAGS=/Zi on the
    nmake command line for --syms builds; command-line wins.

  * dbg2dwf S_OBJNAME.  NT 3.5's linker abbreviates per-module
    sstModule.ModName to relative form (`obj/i386/llmul.obj`); the
    absolute build path lives in S_OBJNAME (CV4 rectyp 0x0009, not
    the CV5+ 0x1101 that windows.h advertises).  Without it, ASM
    CUs landed with DW_AT_comp_dir=`i386` because ml records source
    paths verbatim from its command line.  dbg2dwf now reads
    S_OBJNAME and retroa... (continued)
