Replace debounce package with debounce function from lodash (Me…

…taMask#7931)

These two functions differ slightly in options, but none of those
options are being used by us, so in these cases they're functionally

This was done to reduce the number of direct dependencies we have. It
should not affect bundle size, as we still depend upon the `debounce`
package transitively.
