[SDK] cicuif.h: Add CUIFBitmapDC (#6306)

Supporting TIPs...
JIRA issue: CORE-19360
- Add CUIFBitmapDC class.
- Add cicInitUIFUtil and
  cicDoneUIFUtil functions.
- Add cicSetLayout, cicMirrorBitmap,
  cicCreateDitherBrush,
  cicCreateDisabledBitmap,
  and cicCreateShadowMaskBmp
  utility functions.
