drm/{i915,xe}/panic: move framebuffer allocation where it belongs

Browse source 
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.
