c++: explicit() ignored on deduction guide [PR100065]

When we have explicit() with a value-dependent argument, we can't
evaluate it at parsing time, so cp_parser_function_specifier_opt stashes
the argument into the decl-specifiers and grokdeclarator then stores it
into explicit_specifier_map, which is then used when substituting the
function decl.  grokdeclarator stores it for constructors and conversion
functions, but we also need to do it for deduction guides, otherwise
we'll forget that we've seen an explicit-specifier as in the attached
test.

PR c++/100065

gcc/cp/ChangeLog:

* decl.c (grokdeclarator): Store a value-dependent
explicit-specifier even for deduction guides.

gcc/testsuite/ChangeLog:

* g++.dg/cpp2a/explicit18.C: New test.

What would be mine (but most likely a GCC 12 thing).
