tdf#126665 Remember last used file picker directory

This introduces internal tracking of last used directories.
Each caller of the file picker can pass a "context". The selected
directory will then be saved & restored when opening the file picker
with the same context again.

After ffa636ba74b04b3258ec9a696bc4eac33581fa24 , the Windows file picker
no longer tracks the last used directory itself.
This is a replacement and an improvement at the same time, since there is not
one global last used directory, but one per context.
