EEVEE-Next: Depth Of Field: Improve Temporal stability

This implement a full TAA pass on the depth of field input.
An history buffer is kept for each view needing Depth of field.
This uses a swap with a `TextureFromPool` in order to not always 2
textures allocated.

Since this uses luma weighting without any input, the firefly parameter is
now obsolete and has been removed.

There is some tiny difference with the Film TAA so the implementation is
mostly copy pasted.

Also this implementation uses a LDS cache to speedup the TAA computations.
