PR libstdc++/87308 adjust regex used in std::any pretty printer
The pretty printer for std::any fails when the contained value is a
locally-defined type, because the name in the debuginfo has
cv-qualifiers and ptr-declarators in different positions. The unexpected
format confuses the printer. This makes the printer's regex handle
either format.
This isn't a complete fix because looking up the contained type fails
when there are two types with the same name (defined in different local
scopes). This applies to all closure types defined in a given function,
as they all appear as "func()::lambda" in the debuginfo names.

* python/libstdcxx/v6/printers.py (StdExpAnyPrinter): Adjust regex to
work around PR 88166.
* testsuite/libstdc++-prettyprinters/cxx17.cc: Test std::any
containing a local type.
