Remove CATCH_CONFIG_ENABLE_BENCHMARKING compilation toggle

Now that Catch2 is a proper library, we can always build the full library (comparatively minor slowdown) and the user can avoid including benchmarking headers to avoid the compilation slowdown.

 > [Introduced](https://github.com/catchorg/Catch2/issues/1616) in Catch 2.9.0.

-_Note that benchmarking support is disabled by default and to enable it,
-you need to define `CATCH_CONFIG_ENABLE_BENCHMARKING`. For more details,
-see the [compile-time configuration documentation](configuration.md#top)._
-
 Writing benchmarks is not easy. Catch simplifies certain aspects but you'll
 always need to take care about various aspects. Understanding a few things about
 the way Catch runs your code will be very helpful when writing your benchmarks.
