Switch from Browserify to Webpack

Completely remove attributes to destroy tooltip properly

Remove tooltip update

Destroy is just hiding current tooltip, we also need to remove other attributes to stop showing the tooltip.

The build process is capable of bundling both minimized and unminimized
artifacts for lib-jitsi-meet, jitsi-meet and external_api. However,
there does not seem to be a good reason to (1) always wait for the
building of the two versions and (2) distributing the unminimized
artifacts.

Since the library lib-jitsi-meet does not publish its binaries, it is
always been necessary to produce the binaries i.e. lib-jitsi-meet.js and
lib-jitsi-meet.js as part of the npm install step. Which means that any
modifications to the devDependencies of lib-jitsi-meet's package.json
always have to be reflected in jitsi-meet's package.json. Because
Webpack replaced Browserify in lib-jitsi-meet, Webpack has to become a
devDependency of jitsi-meet.
