Improve and reduce animation player/track editor width.

[WhalesState]

Before:

AnimPL-old.mp4

After:

AnimPl-new.mp4

Definitely looks much better, I like it.

I think it could be set to an even lower value, for example, 80.
UPD: I tried to remove it (in editor using EditorDebugger plugin) and it only affects when right_hb moves to the next "row", so maybe there's no need to set a custom minimum size for it (or just a matter of taste, since it doesn't affect the minimum width of AnimationPlayerEditor).

[WhalesState]

I have added a minimum size for it to give more space for the animation name, previously it looked like this:

After the change it will move the right_hb to the next row instead of shrinking it more than that:

Yes, I understand this.

After the change it will move the right_hb to the next row instead of shrinking it more than that:

Note that the appearance will also depend on the font size (and, I suppose, also on theme spacing).

So in general it is just a matter of taste.

I'm not sure if this is necessary, I haven't seen a unified variant for this in Godot codebase.
The same applies to other similar changes.

This prevents the bottom panel from shrinking down the timeline more than that.

[arkology]

I mean, this is codestyle change and does not affect anything.

It also affects the Curve Editor only when it's visible:

Removing it will result in this when editing curvers:

[arkology]

I understand why this line with set_custom_minimum_size() exists. I mean, changing Size2(0, 150) * EDSCALE to Size2(0, 150 * EDSCALE) is codestyle change and not necessary.

This is faster thank multiplying a float with both x and y for a vector, and is preferred in many other editor classes.

I think it could be set to an even lower value like 100 or 90.

[WhalesState]

This is for the minimum slider width, i already have reduced it from 200 and allowed it to expand horizontally:

200px:

128px:

100px:

At 100 i still can resize it without issue with dragging the slider or using the mouse wheel.

[arkology]

I see. I tried to change it in editor to 100 and below using EditorDebugger plugin.
At least for me, values below 80 look ugly, so I tested 100 and 90, and everything was still fine (saved a few free pixels and still didn't look ugly).

[WhalesState]

Since it supports expanding now, i don't see any issues of using 100px for minimum width.

What we can do to save more space when the fps button is pressed and using seconds like this:

is to choose one of those options to remove Nearest:

Also for Bezier Default Mode:

It can be:

With both changes it will look like this:
