[Bug] LED_MATRIX_CUSTOM_KB and LED_MATRIX_CUSTOM_USER rules.mk variables don't trigger addition of necessary C/C++ defines

[yeroca]

Describe the Bug

When I set LED_MATRIX_CUSTOM_KB = true in my keyboard's rules.mk file, I do not get a corresponding C define generated in cflags.txt. When I look in all of the *.mk files in the tree, I don't see any use or definition for either of these two variables. I would have expected it to be in builddefs/common_features.mk which has the definition for LED_MATRIX_ENABLE.

I have worked around this temporarily by just adding a OPT_DEFS += -DLED_MATRIX_CUSTOM_KB to my keyboard's rules.mk.

I don't think this is related to a specific keyboard or OS, however I'm new here, so please forgive me if I've missed something obvious.
