This allows dependent projects to query the version and location of DXVK
via the pkg-config interface.
The include directories aren't yet set, because the headers aren't
installed; that will follow in a subsequent commit.
The naming of these pkg-config files is based on proposed Fedora packages
for DXVK 2.0, and is not compatible with older Fedora packages for DXVK
1.x (which used the naming convention dxvk-native-d3d9 and so on).
Packagers can create symlinks such as dxvk-native-d3d9.pc -> dxvk-d3d9.pc
if they want to retain compatibility with older names.
