Currently, only usb_pd_protocol.c cares about the actual ccd mode
(disabled/partial/enabled). Everything else just cares whether it's
enabled or not. So promote the boolean ccd_is_connected() from
board/cr50 up to chip/g, and rename it to ccd_ext_is_enabled() to
match the new nomenclature (since 'CCD' itself is now too overloaded).
This will make it easier to handle CCD state directly in board/cr50
after we split it from common/case_closed_debug.c
BUG=none
BRANCH=cr50
TEST=make buildall; boot cr50; make sure USB endpoints still work
