Don't use variable length arrays in wxFileName::ResolveLink()

Browse Source 
Use wxVector<> instead of relying on compiler support for VLAs which is
not standard and shouldn't be required.

This fixes compilation using OpenVMS compiler after the changes of
53bd1391f4 (Add a new wxFileName function to resolve symlinks to
absolute paths, 2021-04-01).
