ComboBox filter reset behavior (clearFilterOnOptionToggle)

[r100-stack]

Changes

Adds on to the patch fix in #2295 to completely address #2276.

Added a new clearFilterOnOptionToggle prop (name bikesheddable) only when multiple is true. Possible values:

• true (default): Filter is cleared when an option is toggled. Useful when users would likely want to re-filter after toggling an option.
• false: Filter is not cleared when an option is toggled. This is useful when users would likely want to toggle multiple options from the same filtered results.

Since the default value is true, which is the existing behavior before this PR, there is no change in the default behavior (no breaking change).

This prop allows the user to choose the behavior since as we see in #2276, both behaviors have benefits.

Testing

• Edited existing story (could create a separate one if needed).
• Added docs. Didn't add an example since that didn't feel necessary and would unnecessarily take up space imo.
• Added e2e tests to test clearFilterOnOptionToggle.

Docs

Added minor changeset.

I didn't have any further comments on this PR at the moment so I'm approving this. I will take a look back when you make changes later.
