UI: Fix scaling of HSV cursor when zooming

The small circle used to choose the hue/saturation and value in the
color widget was drawn with a fixed screen space size. Now scale the
circle used as cursor in the color widget based on the zoom. This
could have been part of a9642f8d6130 but the implementation is
different.

UI: Improve scaling of widgets when zooming

This commit improves the scaling of some ui widgets when
zooming by making the radius of the rounded corners
dependent on the element's zoom level.

Needed to fix T92278 without padding issues, see D13125.

Fix: Property editor icon jittering in some cases

In the tools tab, the tool icon would be offset when it intersected
the bottom of the editor. With some screen resolutions, the icons on
the left side of the editor would also move when intersecting the
bottom of the editor. This happened because of the truncation in
the implicit conversion from float to int. Instead, use explicit
conversion functions.

This patch makes `widget_nodesocket` base the size of the drawn
socket icon on the rectangle that?s passed in to allow it to scale
with the rest of the interface.

UI: Remove extra padding around curve widget

This commit removes the constant padding around to the left and
right of the curve widget. The padding worked in screen space and
didn't take UI scale/zoom into account. This makes the curve widget
consistent with the more recently added curve profile widget used
for bevel profiles.

Geometry Nodes: Add side and fill segments to Cone/Cylinder nodes

This commit extends the 'Cone' and 'Cylinder' mesh primitive nodes,
with two inputs to control the segments along the side and in the fill.
This makes the nodes more flexible and brings them more in line with
the improved cube node.

Fix T88411: Draw frame node text when label is empty

This patch fixes the issue described in T88411, that the text in frame nodes is only shown, when the node has a label. This has been caused by rB8f04ddbbc626, because `node_draw_frame_label` not only draws the label, but also all the other text. Therefore skipping it, when the label is empty, also skips drawing the other text.
This is fixed by moving the check for the empty label into `node_frame_draw_label`.

**Patch:** Frame nodes show text despite not having a label.

UI: Fix widget emboss: Also fade on the right side

Currently the emboss is only fading on left side of the widget,
resulting in the emboss extending vertically on the right side
and ending abruptly. This patch fixes this by also fading the
emboss on the right side and making it symmetric.

Fix T87749 (partially): Text jitter in buttons and spreadsheet editor

This patch fixes jittering text when resizing regions of the UI as
described in T87749. The jitter was caused by the text padding
being stored as an integer which lead to inconsistent rounding.

Most notably this patch fixes the jitter in the new spreadsheet editor,
but not all occurrences of jitter described in T87749 (e.g. in UI lists)
are addressed.
