Cpython build failed with error LNK2001: unresolved external symbol on windows, this error looks start from commit 10f950c9bb0ff4583f361a42aaed562b330e1dba, the previous commit 9846407eaf385917d134ef5e3700c57c59f67684 built successfully.

Repro steps:

1.	git clone https://github.com/python/cpython
2.	Open VS2022 x64 CMD & set _CL_= /fsanitize=address /GS- /wd5072 & set _LINK_= /InferASanLibs /incremental:no /debug
3.	cd /d C:\gitP\python\cpython\PCBuild
4.	get_externals.bat --clean-only
5.	build -e -p x64 -r --no-tkinter -v "/p:PlatformToolset=v143" "/p:WindowsTargetPlatformVersion=10.0.26100.0"

Research direction

Start in PCBuild and the python3tdll.vcxproj target, reproducing the failure with the supplied VS2022, ASan, and build command. Compare commit 10f950c9bb0ff4583f361a42aaed562b330e1dba with 9846407eaf385917d134ef5e3700c57c59f67684 to identify the Windows linker configuration change; done means the x64 ASan build completes without the unresolved externals.
