include/msvcrt: Add noreturn attribute to _assert.

This informs the compiler that no code following an assertion failure
will execute (unless NDEBUG is defined), which increases the accuracy of
compiler warnings and static analyses.

For assert.h, put DECLSPEC_NORETURN before the return type in the
function declaration to remain consistent with other MSVCRT function
declarations.
