Fill in perldelta for CPAN upgrade in commit 45a1388464

Also record that that commit actually upgraded CPAN to 2.05-TRIAL2, not
2.05-TRIAL.
perldelta - Update, remove boilerplates, and do some copy-editing

Also update the template for utilities: a =head3 doesn't look right
directly under a =head1 so make it a =head2 instead.

[perl #121681] fix documentation of delete at the end of an array
perldiag: Clarify non-char warning

What to do in this situation is currently subject to ticket
[perl #121226],  This more clearly documents what happens now.
Avoid double quotes in switchM.t runperl args.

The new tests added in 9fdd5a7ac74817 were sending runperl a -e
command with double quotes around it, which confuses matters on
VMS where arguments get double quotes added unless they already
have them.  The solution is simple: just use the 'prog' parameter
to runperl and let runperl handle the quoting.
Make the test suite pass with -DPERL_DISABLE_PMC

Commit 9fdd5a7ac74817cfaab6 introduced new tests that fail when building
perl without PMC support.  In such cases, skip these new tests.
[perl #121662] use a more stringent check for -DPERL_DISABLE_PMC

which Tom produced updated patch for, but then I grabbed the wrong
patch.
