BREAKING CHANGE: watch APIs now default to use `flush: 'pre'` instead of
`flush: 'post'`.

  - This change affects `watch`, `watchEffect`, the `watch` component
    option, and `this.$watch`.

  - As pointed out by @skirtles-code in
    [this comment](#1706 (comment)),
    Vue 2's watch behavior is pre-flush, and the ecosystem has many uses
    of watch that assumes the pre-flush behavior. Defaulting to post-flush
    can result in unnecessary re-renders without the users being aware of
    it.

  - With this change, watchers need to specify `{ flush: 'post' }` via
    options to trigger callback after Vue render updates. Note that
    specifying `{ flush: 'post' }` will also defer `watchEffect`'s
    initial run to wait for the component's initial render.
