fix(runtime-core): always set invalid vnode type (#820)

Currently, when a component used is not properly registered, we have a warning and the vnode type is set to a Comment type in DEV mode. But in prod mode, we have no default value, making such an application broken and throw a strange error (`can not read _isSuspense of undefined`).

This commit avoids such an error in prod mode (as it is currently the case in Vue 2.x).

fix(build): remove __RUNTIME_COMPILE__ flag

types: remove 'this' annotation from 'get' accessor (#801)

The next version of Typescript disallows 'this' parameter annotations on

      of attributes (class, style, event listeners, a11y attributes, and

refactor(runtime-core): revert setup() result reactive conversion

BREAKING CHANGE: revert setup() result reactive conversion

    Revert 6b10f0c & a840e7d. The motivation of the original change was
    avoiding unnecessary deep conversions, but that can be achieved by
    explicitly marking values non-reactive via `markNonReactive`.

    Removing the reactive conversion behavior leads to an usability
    issue in that plain objects containing refs (which is what most
    composition functions will return), when exposed as a nested
    property from `setup()`, will not unwrap the refs in templates. This
    goes against the "no .value in template" intuition and the only
    workaround requires users to manually wrap it again with `reactive()`.

    So in this commit we are reverting to the previous behavior where
    objects returned from `setup()` are implicitly wrapped with
    `reactive()` for deep ref unwrapping.

    perspective, a custom directive should be scoped to the element and

    instance in the first place.
