Our canplaythrough logic is opaque to the users, so I expect that our recent
change to throttle when we hit the readahead limit would be confusing to users;
those on a slow connection would want their media to prebuffer, and not expect
the download to stop part way through. They would think that Firefox had
stalled at an arbitrary point for some unknown reason, i.e., they'd think
Firefox was broken. So I think we're better to instead only throttle if the
network is good enough that the user probably doesn't worry about the download
not keeping up with playback.
We should restore the previous behaviour on mobile of throttling when the
download reached the readaheadd limit regardless of canplaythrough or network
speed, as the calculus is different on mobile; the user may also be concerned
about battery life, or hitting their data cap. And often the faster the
cellular network is, the more expensive data on it is.
So this patch changes us to throttle when we reach the readahead limit only if
the network is fast, where fast is defined as being able to stream at twice the
rate estimated to be required to playback without stalling.
It also adds a pref to revert to the old behaviour of not considering the
network speed, which we enable on mobile to restore it to its previous
behaviour.

whenever possible since int64_t is ambiguous which could be microseconds
or milliseconds.

There was a cycle amoung a window object -> a HTMLMediaElement -> a MediaDecoder -> a Promise (-> back to the window object).
And we have no way to break the cycle since the MediaDecoder does not participate into the collection.
By moving the Promise form MediaDecoder to HTMLMediaElement, we will be able to break the cycle since the HTMLMediaElement is in the collection.
We'll implement the cycle collection in the next patch.

This mMediaTracksConstructed flag should belong to a MediaDecoder,
every time a HTMLMediaElement switches its MediaDecoder, the flag should be reset to false again.
So, we move the mMediaTracksConstructed flag back to MediaDecoder, by this way,
HTMLMediaElement provides only the mechanism to construct and remove media tracks,
and MediaDecoder uses the flag, mMediaTracksConstructed, to provide policy.

We never suspend videos that is NOT in-tree because we found that, according to the Telemetry data, most (>70%) videos
which are used as the argument of drawImage() are not in-tree. So, by preventing suspending not-in-tree videos, we should
be able to alleviate the pain of not able to resume video decoders synchronously.

So, the MediaDecoder is the one who rules out the policy of suspending video decoder.
We also extract all the policy rules into one single method, MediaDecoder::UpdateVideoDecodeMode().
