Issue #1319 - Resolve RELEASE_OR_BETA questions in all.js

- Enabled SVG transform-box property. I've tested this extensively including the
bug that prevented Mozilla from shipping until 55 which does not seem to apply
to us (most likely a stylo issue). Should be good to go.
- Moved the getRootNode pref to a better place (no change)
- Enabled inputmode property for forms. This is n/a for physical keyboards but
should improve the experience for soft keyboards that can pop up various forms
of input (e.g. numeric) depending on the mode indicated. According to BZ this is
feature complete at our level but was problematic for Android which we don't
have support for anyway.
- Restricted crashing on insecure input of text to debug only.
- Enabled shutting down the async OSFile worker if not used for 30 seconds to
be more conscientious about resource use.
- Enabled blocking of autoplay of media in the background by default, since it
is a saner default to have for the OOBE and is commonly a desired setting by
users (see forum).
- Disabled the storage manager API by default. This fine-grained control over
stored website data is already handled by various extensions and we don't have
the front-end support for it. Assuming this was necessary for Mozilla due to
limited access of WebExtensions to this kind of data.
