hwcontext_vaapi: Add driver quirks to the hwdevice

The driver being used is detected inside av_hwdevice_ctx_init() and the quirks field then set from a table of known device. If this behaviour is unwanted, the user can also set the quirks field manually. Also adds the Intel i965 driver quirk (it does not destroy parameter buffers used in a call to vaRenderPicture()) and detects that driver to set it.
