util: Rename src/gallium/include/pipe/p_config.h to src/util/detect_arch.h

Even though the defines in p_config.h are stared with PIPE_, they are indeed
are generic detecting mechanics, we will rename them to DETECT_* in latter MR

We rename src/gallium/include/pipe/p_config.h src/util/detect_arch.h because
the detect code in src/gallium/include/pipe/p_config.h are most about
processor architecture detecting.

The file util/detect.h is added to replace functional of src/gallium/include/pipe/p_config.h
So we replace of #include "pipe/p_config.h" with #include "util/detect.h"

The file util/detect_cc.h is added as a placeholder for moving compiler related macro defines
from p_config.h into it in following commits
