native: Missing props

**Issue Type:**
Enhancement

**Description:**
Missing props. Also update the docs for these:
- All components
- [ ] `title`

- DataSearch
- [ ] `icon`
- [x] `showIcon`
- [x] `iconPosition`

- ReactiveList
- ~~`sortOptions`~~

- TextField, DataSearch (all input components)
- [x] Add an option to clear the input search value. Probably show an "x" in right corner. (Added with `showClear` prop)
- [x] `autoFocus` prop

- SingleDropdown
- [x] `showCount` doesn't work
- [x] `sortBy` #VALUE! bug
- [ ] Even when not using `defaultSelected`, a value gets selected by default. The default behaviour on Android is the first item in the dropdown gets selected, but the query doesn't get applied. Eg. when using SingleDropdownRange, the first dropdown item that gets selected by default is "Ratings < 3", we still see all results including those with ratings >=3.

- MultiDropdown
- [x] `showCount` doesn't work
- [x] `sortBy` #VALUE! bug
- [x] `selectAllLabel` should disable other selections

- All modal components, date components
(**Added this feature with no prop, please check the example app - DG**)
- [ ] `setValue` prop
- [ ] Displays a visual button that user can tap to confirm the selected value and go back to the main UI. (instead of the user having to press the back key after selection)
- [ ] Can accept `auto` as a value which will move to the main UI as soon as the user makes any selection.
