DrawManager: Adding Custom Render Passes

Currently render passes in the draw manager (eevee) must be predefined
in the render result. This patch would ask the render engine for the
render passes it needs, and create these as a preparation step during
rendering. This allows any draw engine to define more complex render
passes setup.

Render passes can only be added before the call to `RE_engine_begin_result`.
`RE_engine_begin_result` makes a full copy of the render passes. During
rendering the render engines renders to the duplicated passes.
`RE_engine_end_result` syncs the data back to the original render passes,
but only if the passes existed in the original render result.
Currently we work-around this issue by registering the passes in
`render_result_new`. This is legacy blender internal structure and should
be avoided.

With upcoming projects (AOV/Cryptomatte) it becomes a bit of a mess as we
are extending legacy code to support new features. This patch allows us to
let each draw engine register their own render passes at render time
(similar to cycles and other render engines). In the future we could get
rid of legacy render passes registration in render_result_new.

Fix T81079: Switch object ignoring visibility settings

Replace ED_transform_snap_object_context_create with
ED_view3d_give_base_under_cursor & ED_view3d_autodist_simple so object
visibility is respected and non-geometry objects can be supported.

Cleanup: simplify lasso transform from 17cb2a6da0c88

Access as 2D array, loop forwards over the pointer since it's
more common and simpler to read.

Cleanup: avoid error prone nested switch statements (missing break)

17cb2a6da0c88 missed a break statement after a nested switch,
while it didn't cause a bug nesting switch doesn't read well
and is prone to errors like this.

Split modal-keymap checks into their own branch to avoid this happening,
also use matching event checks for all gesture operators.

Fluid: Added obstacle fluid distance parameter

Being able to adjust the distance between fluid and obstacles comes in handy when trying to achieve a fluid motion over inclined obstacles.

Depending on the slope of such obstacles, already small adjustments of this value can help when particles stick to obstacle surfaces (i.e. make particles not stick to obstacles).

UI: Add angle snapping to line gesture tools

This adds support for snapping for line gesture tool. It is implemented
in the modal keymap as Snap, which is a toggle (similar to how snapping
in the transform operator works).

Right now it snaps the angle of the line to 15 degree increments, which
is defined in code. This should be easy to expose in the UI in the future
if we need to.

UI: Move gesture selection with spacebar

This patch adds a modal key to move the selection box/lasso/line while
drawing it. It also sets "repeat": False on the animation playback key
to prevent accidental playback if the spacebar is released after the
mouse button.

EEVEE: Screen Space Reflection: Improve self intersection cases.

This patch fix most self intersection comming from reflection rays.
We regenerate the ray if it goes below the shading normal (should be the

Also add the same precision based bias we use for contact shadows.

SCULPT_tilt_apply_to_normal expects a normal, and offset was already
