[Feature Request]: Establish a single point in the Toolkit where a KryptonCustomPalette is assigned.

[giduac]

Is your feature request related to a problem? Please describe.
At the moment Theme Selector Controls have a property to set the Custom theme and it can also be done through the
ThemeManager and KryptonManager. If there are more locations where this can be done than those should be addressed as well.

If there are other points where this can occur, those should be named here.

Describe the solution you'd like
Consolidate this to a single point in the Toolkit where a custom theme will be assigned.

Describe alternatives you've considered
N/A

Approach

• If there's time in V90 the single point where a custom theme can be set in the tool kit can be developed. In that case all the other entry point can be marked as obsolete and taken from V100 on.
• Setting a custom palette already can be done via KManager. That should suffice and be the default and only way.
• Make this a V100 ticket for now.
