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.

* The TT_SUPPORT_COLRV1 macro is defined to indicate to clients that this
* version of FreeType has support for 'COLR' v1 API. This definition is
* useful to FreeType clients that want to build in support for 'COLR' v1
* depending on a tip-of-tree checkout before it is officially released in
* FreeType, and while the feature cannot yet be tested against using
* version macros. Don't change this macro. This may be removed once the
* feature is in a FreeType release version and version macros can be used
* to test for availability.
