Building with X11 is broken

[finalpatch]

There are 2 issues under X11

• Some Win32 function prototypes are not guarded by {$ifdef Windows}
• A couple symbols in PasVulkan.pas should be 'Xlib' instead of 'X11'

See attachments for my patches.

After these patches the library compiles for me under Ubuntu (still doesn't really work because I tried in VMware which lacks proper driver).
