In preparation of moving the TEST* defines into dr_project_wide_headers.h, we replace all uses of TEST with the equivalent TESTANY. Although we avoid exposing dr_project_wide_headers.h in DR_API headers, it is exposed in drmemtrace's headers where TEST causes collisions with third-party code such as googletest. Issue: #8001
