I noticed that touching MediaDecoder rebuilds a lot of seemingly unrelated
code. This is because HTMLMediaElement includes MediaDecoder.h, and
HTMLMediaElement is included in a number of places. Having HTMLMediaElement.h
predeclare rather than include fixes it.

Since we will remove ChannelMediaDecoder from HLSDecoder's base class, we can't
create HLSDecoder in InstantiateDecoder which returns a ChannelMediaDecoder.

While "debugger" is not available yet, we can enable these debugging APIs for
extensions that have the "tabs" privilege, which includes the Media Panel
Devtools extension, so we/webdev will get better media-playback information.

The MediaStreamGraph relies on having at least one message sent to its message
queue on creation, or it will just sit there and do nothing, and block shutdown
because its not running its rendering loop, so it's not progressing in the
MediaStreamGraph life cycle state machine.
This patch makes sure the `captureStream` will succeed before creating an MSG.

In order to facilitate the movement of code with side-effects called by Element::SetAttr to Element::BeforeSetAttr and Element::AfterSetAttr, Element::AfterSetAttr should have access to the old value of the attribute. This includes information about whether there was previously a value set or not.
Accomplishing this involved passing an additional argument through functions that find and change the old attribute value in order to ensure that we can differentiate between an empty old value and an absent old value (attribute was not set).
Note that while I tried to ensure that accurate values (and their absence) are reported to Element::AfterSetAttr, I largely ignored SVG. While the old value reported for SVG values should be however accurate the value already being reported to SetAttrAndNotify was, SVG elements do not currently report unset values properly because they will never pass a null pointer to SetAttrAndNotify.

Currently, attribute and child arrays (implemented in dom/base/nsAttrAndChildArray.h) start out empty. When cloning, the array ends up being resized multiple times in order to add the attributes and children that are being cloned from the original node. This would be quicker if the array was initialized to the correct size in the first place so that resizes are not necessary.
However, preallocating space for children is only necessary when performing a deep clone. Therefore, an additional parameter is being added to the Clone, CopyInnerTo, and CloneDocHelper methods to indicate whether preallocation of children should happen. Attributes are copied either way, so that part of the array is preallocated in both cases.

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.
