Restriction of the nodes api to clearly define never-null function arguments.
Side effects: some assertions and null-check (with early return) were removed.
On the caller side is ensured to never derefer null to pass argument (mainly in RNA).
In addition, one pointer argument now actually a return type.
By-reference return types instead of pointers going to be separate kind of
change since also imply of cleaning up variables created from reference.
Also good future improvement would be to mark a copy-constructor as
explicit for DNA node types.

This removes the second to last usage of `NOD_static_types.hh` which we intend
to remove. A nice benefit is that the idname is now finally more explicit when a
node is registered. Previously it was difficult to search for the definition of
a node in the code when one had only the idname, which is the main identifier
for nodes.
The main change is in `node_type_base`.

As part of an effort to remove this header, reducing the need for macro/
include magic and making node definitions more independent, move
the node UI name and description definitions to each node's file.
The UI name, description, and idname are also moved to std::string
instead of char arrays.
Similar to b43e2168e3.

A followup for 5e7f3e5c84.
Make the NOD_static_types.h file less important by moving `enum_name_legacy`
to be defined in the register function of every node. This helps our gradual transition
away from this file.
Also add a fallback to the node idname so that newly added nodes no longer need
to define the string value.

The additional division modes were implemented with float
division then rounding to match float > int conversion in
existing float to int node.
As pointed out in the bug report the precision here is limited.
This patch replaces the float division with integer math which
increases the precision to much higher numbers.
Divide Round by due to the way it is calculated has less precision
than Divide Floor and Divide Ceil.

Provide building block support for integer operations.
Manipulation of integer based data should not be limited to using float math nodes.
Using float math comes with accuracy issues for larger integers and requires unnecessary
type conversions.
The node also adds some integer specific operations like GCM and LCD.
