Features: Extend concept to C language. Add properties and variables corresponding to CXX equivalents. Add features for c_function_prototypes (C90), c_restrict (C99), c_variadic_macros (C99) and c_static_assert (C11). This feature set can be extended later. Add a <PREFIX>_RESTRICT symbol define to WriteCompilerDetectionHeader to conditionally represent the c_restrict feature.

C_STANDARD_REQUIRED
-------------------
Boolean describing whether the value of :prop_tgt:`C_STANDARD` is a requirement.
If this property is set to ``ON``, then the value of the
:prop_tgt:`C_STANDARD` target property is treated as a requirement. If this
property is ``OFF`` or unset, the :prop_tgt:`C_STANDARD` target property is
treated as optional and may "decay" to a previous standard if the requested is
not available.
This property is initialized by the value of
the :variable:`CMAKE_C_STANDARD_REQUIRED` variable if it is set when a
target is created.
