Missing "p-clickable" class in MultiSelect trigger icon

[InmaInno]

Describe the bug

Describe the issue
The p-clickable class seems to be missing in the MultiSelect trigger icon (and possibly in other interactive elements).

Additional context
If this is intentional, could you clarify in the documentation? Otherwise, please consider adding p-clickable back for consistency.

Steps to reproduce the behavior

Expected behavior

All interactive elements (e.g. icons that trigger actions) should include the p-clickable class for consistency and expected behavior (cursor pointer, etc.).
