[PATCH v2] libcamera: controls: Generate macro for each control

[Barnabás Pőcze]

Generate a macro in the form of LIBCAMERA_HAS_$VENDOR_VENDOR_$MODE_$NAME
for each control so that its existence can be checked easily and without
extra version checks.

changes in v2:
  * rename macro from `LIBCAMERA_HAS_$VENDOR_$MODE_$NAME` to
    `LIBCAMERA_HAS_$VENDOR_VENDOR_$MODE_$NAME` so that has the
                          ^^^^^^^
    name of the macro already generated for the control namespaces
    as prefix
