Firebird 3.0.13 Win32: KERNEL32.GetThreadId import breaks Windows XP (regression vs 3.0.12)

[gobbo67]

Environment:

• Windows XP SP3 32-bit (legacy internal testing)
• Firebird Win32 ZIP kits:
  • 3.0.12.33787-0: OK
  • 3.0.13.33818-0: FAIL

Problem:
On Windows XP, Firebird 3.0.13 Win32 binaries fail to load with:
“The procedure entry point GetThreadId could not be located in KERNEL32.dll”.

Evidence (dumpbin on Windows 11):

• 3.0.12 fbclient.dll: does NOT import GetThreadId
• 3.0.13 fbclient.dll: imports KERNEL32.dll -> GetThreadId

In 3.0.13 Win32, these files also import GetThreadId:

• fbclient.dll, firebird.exe, fbguard.exe, fb_lock_print.exe, plugins/engine12.dll, plugins/fbtrace.dll
  (our quick check: gbak.exe does not import GetThreadId)

This looks like a regression introduced between 3.0.12 and 3.0.13 (not an installer/VC++ redist issue).

Maintainer mentioned this may be caused by backporting fix #8403; please confirm and/or point to the exact commit.

Should be fixed now

We verified 3.0.14 x86 snapshot: GetThreadId imports are gone (fbclient/firebird/etc. are clean), but on Windows XP SP3 the binaries now fail to start with: api-ms-win-crt-runtime-l1-1-0.dll was not found
This suggests the new toolchain/CRT no longer supports XP, so even with the GetThreadId fix, Firebird 3.0.14 Win32 is still not runnable on XP
