cmake: allow to specify compliler for DTS preprocessing MWDT CCAC compiler can't handle the dts file as gcc does, so allow to specify compliler for DTS preprocessing which is differ from ${CMAKE_C_COMPILER}. Use ARC GNU compiler for DTS preprocessing in case of MWDT toolchain. Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com>

# MWDT compiler (CCAC) can't be used for preprocessing the DTS sources as it has
# weird restrictions about file extensions. Synopsys Jira issue: P10019563-38578
# Let's temporarily use GNU compiler instead.
