WIdgets: Enqueue scripts on `'wp_enqueue_scripts'` hook

[r-a-y]

In our widgets that contain enqueued JS, we currently do not hook the JS on 'wp_enqueue_scripts'.

We should do this to avoid enqueuing too early and to also remove checks on admin pages.

Patch looks good, why not hooking to bp_enqueue_scripts ?

Good call! Will make the change and commit.

Widgets: Enqueue JS on 'bp_enqueue_scripts' action.

Previously, we were enqueuing our JS too early resulting in our JS being
loaded on embed pages.

Fixes #7087.
