[CMake] Remove compiler flag overrides and support for C language.

Browse source 
The setting of overrides was broken (the CXX flags were not set but
the C flags were) and we aren't even using the C compiler any more.

The C compiler is used by the example C project but that is built
as an external project now so we don't need C support anymore.

The setting of defaults was also very fragile. CMake has quite
complicated support here (e.g. MSVC with a clang based tool chain) which
would likely not work properly with the override approach as it existed.

This means we loose some of the custom linker flags we were setting for
MSVC but we were never doing a great job of replicating the exact set of
flags used in the old build system anyway. Subsequent commits will
gradually fix this.
