Add config option to test for 'COLR' v1 support in headers. * include/freetype/config/ftoption.h (TT_SUPPORT_COLRV1): New macro so that clients can test whether the FreeType checkout that they are building against supports the 'COLR' v1 API. This is intended to be a temporary solution until 'COLR' v1 support is released in a FreeType version and such a check can be made by using the version number instead.
