[DMN Designer] Search feature - Highlight the current result with colors that follow the PF standard

All places (DMN Boxed expressions editor, Guided Decision Tables editor, Guided Decision Tables graph editor, and DMN Data Types tab) that use the search component must follow the PatternFly standard colors to highlight the cells.

Apply the infrastructure code from https://issues.jboss.org/browse/DROOLS-4406 to highlight the grid cells, and pure CSS to highlight the Data Types.

BG: #F9D67A
Stroke: #F5C12E

⚠️ Notice:
The DMN graph stay as is for now. Since nodes can have their own colors, the current highlight is enough.
