gcov: use no-op functions if not enabled
Instead of wrapping every gcov function call in an ifdef.
Note: The usage of `((void)0)` is based on section 7.2 of the C99
standard (N1256)[1] [2]:
> 7.2 Diagnostics <assert.h>
>
> 1 The header <assert.h> defines the assert macro and refers to another
> macro,
>
> NDEBUG
>
> which is not defined by <assert.h>. If NDEBUG is defined as a macro
> name at the point in the source file where <assert.h> is included, the
> assert macro is defined simply as
>
> #define assert(ignore) ((void)0)
See also assert.h(0p) from POSIX.1-2017[3].
Note: This is a continuation of commit b408b20c7 ("gcov: fix build
failure with gcc 11.1.0") / PR #4373.
