EEVEE: Depth Of Field: Add new jittered Dof

This is a new method to increase quality of the Depth of field.

This works by jittering the camera for every sample. This needs a lot of
samples to converge to something smooth. The new overblur parameter is
introduced to blur each sample to make it noisefree faster at the cost
of accuracy.

EEVEE: Depth Of Field: Reintroduce the extra offset for convolution

This is really needed for watertighteness and avoid background leaking.

EEVEE: Depth Of Field: Fix orthographic view Circle of confusion

Orthographic view depth of field was broken since day one it seems.

EEVEE: Depth Of Field: Gather: Fix tiling artifact on foreground

Was caused by wrong tile prediction.

EEVEE: Depth Of Field: Gather: Fix polygonal dof radius being too big

The polygonal bokeh was outputing normalized UV but not the normal one.

EEVEE: Depth Of Field: Lower minimal CoC radius for scattering

Makes possible to have sharper bright spots.

EEVEE: Depth Of Field: Cleanup: Share more define

EEVEE: Depth Of Field: Cleanup: Add resolve pass description

EEVEE: Depth Of Field: Tests: update shader tests

EEVEE: Depth Of Field: Cleanup: Share defines between C and GLSL

EEVEE: Depth Of Field: Fix fast gather tiles bleeding color

Seems like the dilation is too small for fast gathering to not bleed.
Introduce an arbitrary factor to fix this issue.

EEVEE: Depth Of Field: Add high quality slight defocus option

This option is needed to avoid bumping the scene samples really high to
mitigate the noise and flickering introduced by slight defocus areas.

EEVEE: Depth Of Field: Cleanup: Change precision of dof parameter

EEVEE: Depth Of Field: Fix jump in appearance when using bokeh texture

This was caused by a missing factor of 2.
Also fix issues with scatter bokeh size.
Remove fast_sqrt because it does not give the correct bokeh size and
cause noticeable jump between ratio = 1 and ratio > 1.

EEVEE: Depth Of Field: Fix apparent tiles on foreground limits

EEVEE: Depth Of Field: Add denoising pass to stabilize bokeh highlights

Alike in the reference implementation, we stabilize the convolution
input. However, instead of a fullblown TAA pass, we just do neighborhood
clamping to avoid very bright pixels. We filter only spatially and not
temporaly.

EEVEE: Depth Of Field: Resolve: Fix slight focus gather radius too big

This improves performance a bit.

EEVEE: Depth Of Field: Scatter Add UI options

The neighbor max tooltip could be less vague.

EEVEE: Depth Of Field: Revert fix scatter power difference

Scatter only seems to have an intensity difference because gather is
only underestimating the highlights. But the scatter bokeh are correct.

EEVEE: Depth Of Field: Fix neighborhood rejection

The samples were offseted and the difference wasn't absolute.
