  [CSSPGO] Explicitly disallow Binary and Compact Binary profile format for CSSPGO

CSSPGO only supports text and extended binary profile now. Raw binary does not have the metadata section CSSPGO needs, and Compact binary profile needs special handling for GUID based context names, which is not yet implemented.

Disasslow these two format for CSSPGO profile writing to avoid silently generating invalid profiles.
