drm/xe/irq: Manage MSI-X interrupts allocation

drm/xe/irq: Manage MSI-X interrupts allocation

Expose functions to request and free MSI-X interrupts.

The request has two flavors:
- Static MSI-X allocation, for known MSI-X interrupts (e.g. GuC-to-host)
- Dynamic MSI-X allocation, which uses the next available MSI-X interrupt
