Eevee: Add Volume Transmittance to Color Render Passes.

In Cycles the volume transmittance is already composited into the color
passes. In Eevee the volume transmittance pass was separate and needed
to be composited in the compositor. This patch adds the volume
transmittance pass direct in the next render passes:

* Diffuse Color
* Specular Color
* Emission
* Environment

This patch includes the removal of the volume transmittance render pass.
It also renames the volume render passes to match Cycles. The setting
themselves aren't unified.

UI: Click modifier icon to set active modifier

This should be a final piece of the changes for the active modifier
interface. Before, it was necessary to click on the blank space of a
modifier panel to set it active (not the header), this commit allows
clicking on the icon also.

The spacing with the spacing with the expand button would ideally
be a bit larger, but the layout system doesn't offer much flexibility
here.

Fix T83673: Custom node trees selectable in nodes modifier

Node tree types from addons were selectable in the modifier's drop-down.
Obviously they didn't do anything, but it shouldn't be possible anyway.
This was just caused by an unimplemented poll function.

Fix T83725 Inconsistent vertex group between exact and fast boolean.

This makes the exact boolean have zero weights for any vertex groups
on any newly created vertices, which is what the fast solver does.

The exact boolean solver was interpolating vertex data when interpolating
loop data in newly created faces. Not sure why I chose that. The Fast
boolean solver doesn't do that, so I stopped doing it too.

Cleanup: removing some uses of equal sign in descriptions

Fix weird Swing+Twist decomposition with noncanonical quaternions.

It turns out that after the fix to T83196 (rB814b2787cadd) the matrix
to quaternion conversion can produce noncanonical results in large
areas of the rotation space, when previously this was limited to
way smaller areas. This in turn causes Swing+Twist math to produce
angles beyond 180 degrees, e.g. outputting a -120..240 range.

This fixes both issues, ensuring that conversion outputs a canonical
result, and decomposition canonifies its input.
