Mike Kaganski 599ab8dc3a Rename con-const vcl::Font property getters for clarity 
There are two sets of getters there; and the non-const ones may copy
the COW mpImplFont, and may call its AskConfig.

The name overload is unfortunate. It is not obvious at the call site,
which of the two will be called; and what is different. IMO, the way
to fix it would be to keep only one set of getters (the const one),
and make the call to AskConfig explicit (in the places that set font
name, and know that resolution of other properties will be needed).

But in this change, I only rename the non-const getters, making sure
to keep the behavior unchanged (at least the intention is to have a
non-functional change, meaning that the places that called non-const
overload, now use the renamed functions), to make it clear where we
actually may copy and initialize it.
