panfrost/lima/panvk: Define a common vendor ID

Rusticl reports `CL_DEVICE_VENDOR_ID` using the `vendor_id` property
defined in Panfrost. The value is not set so a `0` is reported
instead.

Initialise the value to `0x13B5`, which is Arm's PCI vendor ID.

Add the definition in `lib/pan_props.h` so it can be shared with
Gallium Lima, Panfrost and PanVK.
