new 'use VERSION' warnings in some core modules

[iabyn]

Description Since v5.39.7-198-g351de214d2, with the the addition this warning:

use VERSION while another use VERSION is in scope is deprecated

a number of core modules have started emitting this warning on stderr during perl's 'make test'. It would be good to get these silenced before 5.40. Here's the relevant output from 'make test':

lib/B/Deparse .................................................... use VERSION while another use VERSION is in scope is deprecated, and will become fatal in Perl 5.46 at (eval 211) line 17, <DATA> chunk 157.


dist/Devel-SelfStubber/t/Devel-SelfStubber ....................... use VERSION while another use VERSION is in scope is deprecated, and will become fatal in Perl 5.46 at (eval 5) line 1.

I can possibly find time to look at these some evening of my vacation but if not I'll be happy to review anyone else's PR if they get there first ;)

I took a look at these warnings, but they're all outside my skill set to resolve. Except for lib/Deparse.t, the warnings are all emitted as soon as the test starts to run. B::Deparse requires knowledge of the internals that I lack. And I have never used Devel::SelfStubber or SelfLoader (which are intertwined). Tried commenting out the sub Version {$VERSION}; in their respective *.pm files; that made no difference.

So, this is going to require some expert attention.

I believe that @haarg's branch clears up these failures (though CPAN may be a different story, see https://github.com/Perl/perl5/issues/22013).

At current blead:

$ ./perl t/harness lib/B/Deparse.t 
../lib/B/Deparse.t .. ok     

$ ./perl t/harness dist/Devel-SelfStubber/t/Devel-SelfStubber.t 
../dist/Devel-SelfStubber/t/Devel-SelfStubber.t .. ok     

$ ./perl t/harness dist/SelfLoader/t/0*.t
../dist/SelfLoader/t/01SelfLoader.t ........ ok     
../dist/SelfLoader/t/02SelfLoader-buggy.t .. ok   
../dist/SelfLoader/t/03taint.t ............. ok     

So I believe the core tests at least are fine. We can close this?

Yeah, STDERR no longer noisy.
