package/binutils: handle gprofng as an optional feature

binutils 2.39 added support for gprofng, a new profiler (see
https://www.phoronix.com/news/GNU-Profiler-gprofng).

This new profiler is enabled by default, but it requires bison on the
host.

In order to handle this, this commit:

 - Adds a new option BR2_BINUTILS_GPROFNG, which allows to
   enable/disable gprofng in host-binutils

 - Unconditionnally disables gprofng for the target binutils, based on
   the idea that in a Buildroot context the analysis of profiling data
   is generally done on the host system. This can of course always be
   revisited later by adding a new option to the target binutils
   package.
