mesa: Implement KHR_debug ObjectLabel functions

V3: make sure to add null terminator when setting label,
generate error when the client specifies an explicit
length that exceeds MAX_LABEL_LENGTH, set label pointer
to NULL when freed, and output correct length in
MAX_LABEL_LENGTH error message.

V2: fixed indentation of comment
