devel/binutils: Update from 2.39 to 2.40

Update our binutils port from 2.39 to 2.40.

Enable zstd support. Depend on the port in case the port is newer
than base.

Additional contributions by dizzy@:

- Use DISTVERSION instead of PORTVERSION
- Drop (reset) PORTREVISION
- Define zstd as LIB_DEPENDS rather than DEPENDS
- Add USES= localbase pkgconfig to fix (lib)zstd detection
- Set zstd as default compression algorithm for compressed debug
  sections
- Enable verbose output during build
- Drop STATIC option, it's unsupported upstream and fails to build

Also, disable tests because --compress-debug-sections is always set
to zlib-gabi regardless of the compression setting by ./configure,
resulting in failure.
