Fix T84638: Wrong scale for primitives with radius

Creating some primitives allows for a scale value (via python) that will
scale the object accordingly. For objects with a radius parameter
(like cylinders, spheres, etc.) passing a scale different to (1,1,1)
would result in unexpected behavior.

For example:
`>>> bpy.ops.mesh.primitive_uv_sphere_add(radius=2, scale=(1,1,2))`
We would expect this to create a sphere with a radius of 2
(dimensions 4,4,4) and then be scaled *2 along the z-axis
(dimensions 4,4,8). But this would previously create a scaled sphere
with dimensions (2,2,4).

The scale was simply divided by two. Maybe because the "radius"
parameter for creating the primitives was confusingly named "diameter"
(but used as the radius).

The fix adds a scale parameter to `ED_object_new_primitive_matrix`
and also renames the wrongly named "diameter" parameters to "radius".

UI: Add light count to viewport statistics

Even though lights were part of `SceneStats`, they were not used when
rBfd10ac9acaa0 was committed.

This patch adds the light count back into the statistics. When a light is
the active object, it will display the total number of lights in the
scene, as well as how many lights are currently selected.

VSE: Add tooltips for add_effect_strips operator

This patch adds propper tooltips to the effect strips in the "Add" menu.
Note that not all effect strips are actually in the "Effect Strips"
submenu like color strips, text strips or transitions. For these types
of effect strips, a dediacted tooltip is especially useful.

Fix T89265: Crash when tabbing through num inputs

Fix by reverting the part of ec30cf0b742f5181c4de91b474ca01d6a809c593
that assigned `but->editval` in `ui_numedit_begin_set_values`.

Causing access freed memory when using tab to switch
to a numeric input and then leaving the textbox by clicking outside.
This was because `ui_numedit_begin_set_values` shouldn't need to set
`but->editval` and overwrite the pointer.
This would set a pointer that had previously been freed,
causing a `NULL` check to fail later on.
