[siw] Add search.searchOnType preference

[DucNgn]

What it does

Fixes: #8774.

• Add search.searchOnType preference to control whether or not to search as a user updating search term.
• Add search.searchOnTypeDebouncePeriod preference to control the timeout in milliseconds between a character being typed and the search starts. Has no effect when search.searchOnType is disabled.

As a user, I want to control if typing in the search input box would trigger the search action. For example, sometimes, it's better if it waits until I have finished formulating the regex query.

How to test

• search.searchOnType:

  • Enable search.searchOnType
  • Open the search view
  • Typing in the search input box triggers the search and the results appear in the search view
  • Disable search.searchOnType, then the search only starts when user press ENTER in the search input box

• search.searchOntypeDebouncePeriod:

  • Make sure searchOnType is enabled
  • Adjust the value (in milliseconds)
  • Start typing in the search input box
  • When user stopped typing, the search starts after the set debounce period
