I've updated this to drop MLIR_INCLUDE_DIR now. Note that there already is MLIR_INCLUDE_DIRS, which is set up correctly depending on whether it's the installed or the build-tree config.

I've dropped the MLIR_INCLUDE_DIR use for FIROps.td because I don't think it's actually necessary. We already add the MLIR_INCLUDE_DIRS to the include directories at a higher level, so we don't need to do so again here. (Otherwise I could switch this to use EXTRA_INCLUDES with MLIR_INCLUDE_DIRS.)
