Move the panic handling to the display parent interface, making display
more independent of i915 and xe driver implementations.

Add a special path for VRAM using xe_res iterators to ensure a panic
screen is shown on VRAM as well.

The intel_panic_finish() function really needs the struct intel_panic
pointer, not struct intel_framebuffer. Make it so.

The struct intel_framebuffer allocation naturally belongs in intel_fb.c,
not hidden inside panic implementation. Separate the panic
allocation. Drop the unnecessary struct i915_framebuffer and struct
xe_framebuffer types.

Prepare for better shared interfaces between panic implementations. The
struct intel_panic remains an opaque data type, with unique
implementations in i915 and xe.
This allows us to change the panic data pointer from void * to struct
intel_panic *, helping type safety.

Add a panic data pointer member in struct intel_framebuffer in
preparation for breaking the artificial subclassing between
intel_framebuffer and panic structures.

Rename the intel_bo_panic_*() functions according to the functionality,
dropping the misleading intel_bo reference.
Keep intel_bo_alloc_framebuffer() for now; it'll be refactored later.

intel_bo.[ch] is not the appropriate location for the panic
functionality. Split out intel_panic.[ch] and xe_panic.c in i915 and
xe. Keep the function names for now.
