[Combo]: $clear-button-background and $clear-button-foreground theme function parameters are not working

[adrianptrv]

Currently, the $clear-button-background and $clear-button-foreground parameters in the Combo theme function are not working as expected. Although the passed values are assigned to variables, the clear button in the Combo component is currently receiving its colors from the --input-suffix-color--filled and --input-suffix-background-filled variables, instead of the --clear-button-background and --clear-button-foreground variables.
