Point Separate Node: Change has_attribute function

Point separate node: Refactor, add comments, clean up

Make more of the logic generic so that it can more easily work on more
component types in the future. Basically anything that handles attributes
can be generic.

Attribute Access: Add a "has_attribute" method

Point Separate Node: Revert earlier change to point cloud creation

I'm not quite sure creating the "radius" attribute in here is necessary
when any other attribute can be created later, but without this the
original radius attribute didn't pass to the new point cloud components
properly.

This should be investigated though, because the "radius" attribute
of pointclouds currently exists in some "semi-built-in" space that
doesn't really make sense.

Geometry Nodes: Point separate node

This node takes an input geometry and ouputs two geometries, moving
some points to the first and other points to the second depending on a
mask attribute input and a threshold.

The implementation tries to be "attribute component agnostic", meaning
it should be relatively easy to add "separate" functionality for more
component types in the future when they need to support it. (Then the
node could be renamed "Separate Geometry").

There is still an error carrying over the values for some attributes to
the output geometries.

UI: Add new node colors for geometry nodes

During the development of the new nodes in the `geometry-nodes` branch
the color of the new nodes wasn't considered, so all of the nodes ended
up red, the color for "input" nodes. This patch introduces two new
colors, one for "Geometry" and one for "Attributes". There are only two
attribute nodes currently, but the next sprint will add two more,
attribute mix, and sample from texture. The attribute nodes are
conceptually different enough from the nodes that modify the geometry
that they deserve their own color.

Differential Revision: https://developer.blender.org/D9682

Geometry Nodes: support swapping inputs in function nodes

This is the same fix as in rB5ae666c2cc67be0e5ffb897c1ff48fe434d7dbc6.

Geometry Nodes: automatically reconnect when swapping inputs

This makes it easier to swap the inputs to the Join Geometry node.
The behavior is the same as in the Math node.

Geometry Nodes: correct modifier name when creating from node editor

The name should be the same as when the modifier is created in the
modifier tab of the properties editor.

Cleanup: Store "is_active" instead of pointer property in panel type

This is consistent with the way other panel type fields are stored.

Merge remote-tracking branch 'origin/master' into geometry-nodes

Cleanup: add a comment

Merge branch 'master' into geometry-nodes

Cleanup: correct function name

Geometry Nodes: Change modifier name

The modifier was called "Empty", which reflects the fact that the modifier
doesn't do anything when you add it. However, that is not true after you
change the modifier's node group, and the fact that the modifier uses
nodes is the one thing that distinguishes it at this point. This commit
changes the name to "Geometry Nodes", which is simple and consistent
with the "Geometry Node Editor" and the naming of the project so far.
