SWDEV-380238 - hipcc passes incorrect device lib path to clang on win…

…dows (#3150)

hipcc should not pass --hip-device-lib-path to clang by default so that clang
decicde device lib path by itself.

hipcc only passes --hip-device-lib-path to clang if env var DEVICE_LIB_PATH
is specified.

DEVICE_LIB_PATH should be depricated in the future and users should use
--hip-device-lib-path instead.
