add_custom_command: Target-dependent generator expression support

Browse Source 
OUTPUT variant with a TARGET given to allow resolving target-based generator
expressions wouldn't work because OUTPUT is resolved before generator targets
are created, i.e. FindGeneratorTargetToUse() returns nullptr.
This is a known limitation, see #21364.

Implements #21336.
