Clément Foucault 12095b8e16 EEVEE-Next: Irradiance Cache: Use scene bounds for surfel cache 
This remove the per irradiance grid approach. The idea is to do the light
transport only once for each visibility collection and store the
irradiance for all irradiance grid using this visibility mask.

This removes the need for the lightprobe near/far clip parameters.

Clément Foucault 34adebcf43 GPU: FrameBuffer: Fix empty framebuffer update 
The framebuffer default size was only set during the first bind. This
is because the `dirty_attachments_ tag` wasn't set and thus the
framebuffer size was never passed down to the GL.

Split to `default_size_set()` to not affect other code paths that use
`size_set()`.

Clément Foucault bfeb1a1a8d EEVEE-Next: IrradianceBake: Fix light bounce 
Light bouncing needs a feedback mechanism. We cannot reuse the same
radiance for scattering light and accumulating it.

This splits the final accumulation to `radiance` and bouncing light into
`incomming_light` and `outgoing_light`.

Clément Foucault 5de76bbbff EEVEE-Next: IrradianceBake: Fix light-leak

The fix consists in clumping more surfel together when creating the lists
then rewire the coplanar surfels to more valid surfels up and down the
same list.

Clément Foucault 408c5d7281 EEVEE-Next: Irradiance-Cache: Add surfel placement 
Spawning surfels uses a new shader pipeline (called `capture`) to avoid
the complexity of modifying the deferred or forward pipeline.
The shaders are light to compile and should only be compiled on bake.

This is very WIP: the surfel projection box is hardcoded and the 3
projections are done every frame. The surfels are placed in a regular
grid because of the raster pipeline used to spawn them.

Note: While this is really fast, I am not sure this will scale well for
highly detailed lighting conditions. In the case where the surfel density
is too low, the aliasing might create really poor result.
