243af2ff - [LLDB][test] Improve SHELL detection on Windows in Makefile.rules (#99532)

[LLDB][test] Improve SHELL detection on Windows in Makefile.rules (#99532) In MinGW make, the `%windir%` variable has a lowercase name `$(windir)` when launched from cmd.exe, and `$(WINDIR)` name when launched from MSYS2, since MSYS2 represents standard Windows environment variables names in upper case. This commit makes Makefile.rules consider both run variants.
