Move the build to VS2022 (v143) with runtime parity against VC9

Hand-converted the four .vcproj projects to .vcxproj (Win32, v143,
Windows 11 SDK + DXSDK June 2010 for d3dx9/dxerr only). WinTesla.sln now
builds the v143 projects; the legacy solution is kept as WinTesla_vc9.sln.

Kept: /Zp1 in Munga_L4+RP_L4, Unicode, x86, /DYNAMICBASE:NO,
/FORCE:MULTIPLE (header-defined globals still duplicated across TUs).
Changed: CRT unified to /MD(d); import libs linked by the exes instead of
merged into Munga_L4.lib; WINDOWS_IGNORE_PACKING_MISMATCH and
_SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS defined;
legacy_stdio_definitions.lib for the June-2010 dxerr.lib.

Source fixes, all behavior-preserving: Time gains standard (non-volatile)
copy-ctor/assignment overloads (rvalues cannot bind to volatile& in
standard C++); operator==(SOCKADDR_IN&,...) made inline; L4DINPUT's
Enum*Callback pair renamed DIEnum* (collided with L4CTRL's under LTCG);
std::ios.in -> std::ios::in in CAMMGR.cpp.

Verified: VC9 baseline rebuilt from this tree first, then the v143 build
compared against it in a sandboxed game working copy - identical logs and
behavior through RIO init (against vRIO) and mission load, including the
same pre-existing AV in d3d_OBJECT::LoadTexture (L4D3D.cpp:262) that both
toolchains hit; documented in BUILD.md 4 as the next debugging target.
