In flutter/engine main branch, commit ref: 5c76075

I try to set up the engine developing environment on windows 10, setting env value to GYP_MSVS_VERSION=2022, and then gclient sync, this error shows:

src/flutter/tools/dia_dll.py'
line 55, in GetDiaDll()
return os.path.join (dia path, DIA_DLL[msvs_version])
KeyError:
'2022'
