Return all information from wxListCtrl::GetItem() if no mask specified.

version behaviour.

Closes #3666.

Allow viewing read-only long string wxPropertyGrid properties values.

When wxLongStringProperty is read-only, it should still be possible to view
its value by opening the dialog normally used for editing it, otherwise this
value cannot be seen (nor copied, which is also useful sometimes) at all.

Closes #14945.

Remove spurious MSVC check around wxDF_HTML code in wxMSW.

For some reason, support for wxDF_HTML in clipboard code was disabled for
non-MSVC compilers. Enable it now as it's not compiler-specific at all.
