Move URL<->filename conversion functions to wxFileName

Browse Source 
This ensures that they are always available and can be used in
wxLaunchDefaultBrowser() in all build variants, whereas before this
function didn't handle file:// URLs correctly when the library was built
with wxUSE_FILESYSTEM==0.

Closes https://github.com/wxWidgets/wxWidgets/pull/1469

Closes #10414.
