ui5-combobox : custom filter

[Vasu-p]

Is your feature request related to a problem? Please describe.
Currently there are three filters to choose from. It can be restricting if we wanna implement something else which doesn't fit with those.
For example, I would like to generate the options of the combobox dynamically by filtering over a list of json objects. And I might want to show one of the fields of the object but allow user to filter also by typing other non-visible fields. This is currently not possible as the drop down only shows those options which match the current filter settings.

Describe the solution you'd like
an option for passing our own custom function to the filter prop.

Hey @Vasu-p

We introduced a None filter to the ComboBox so application can filter items using the input event of the combobo/multicombobox.
