Add option to toggle console window

Curve: Prevent forcing 1.0 min value to 0.99

The setters are called when the property is first initialized, and before
that its default min and max are 0.0 and 1.0 respectively.

If you configured min_value to 1.0 and max_value to e.g. 3.0, since the
min_value setter can be called before that of max_value (which thus still
defaults to 1.0), the min will be set to 0.99.
Same conflict could happen with a configured max_value of 0 if its setter
is called before that of a valid, negative min value.

Particles: Fix uninitialized angular velocity, fix inconsistency in linear velocity between CPU and GPU Particles

Improve the `Engine.get_version_info()` documentation

Right now it would take garbage values when loading scenes,
which could end up written to the scene file.

This documents some keys that were missing and improves formatting.

Fix some editor crashes

Multicast, more network interfaces info

Allow getting interfaces names and assigned names.

On UWP this is not supported, and the function will return one interface
for each local address (with interface name the local address itself).

Remove always true/false values

Document ReferenceRect Node

This is an editor setting and its value can also be toggled
using an entry in the Editor toolbar. The console will still
appear briefly when starting the project manager or editor,
as it's still compiled as console application.

Does not impact exported games, which will still run without
console in release and with console in debug mode.

A project setting or export option could be added to disable
it in debug mode if there's demand for it, but that would
greatly reduce the usefulness of debug builds if Windows users
can no longer report error and crash messages.

Fixes #17889.
