cmake: Toolchain abstraction: Assembly

Browse source 
Introduce toolchain_cc_asm macro to capture toolchain specific flags
related to assembly.

-D_ASMLANGUAGE is kept common for all, assuming -D as define flag is
supported by all compilers (which is almost the case).

No functional change expected.

Clang's flags are compatible with gcc, and are thus inherited.

This is motivated by the wish to abstract Zephyr's usage of toolchains,
permitting easier porting to other (commercial) toolchains.
