This commit is a prerequisite for part 5 of this patch set.
The idea is to keep the information whether the last
load done by the doc shell was a same-document navigation.
The value is reset for every navigation, therefore it
should always be correct.
There is no changed behavior in this commit.

`PresShell::GetRootScrollFrameAsScrollable()` is equivalent to
`PresShell::GetRootScrollContainerFrame()`.
In ScrollContainerFrame.h, `DecideScrollableLayer()` has two versions, one has
four parameters, and the other has five parameters with the fifth parameter
`aDirtyRectHasBeenOverriden` having a default value `nullptr`. When we switch
the caller from `nsIScrollableFrame` to `ScrollContainerFrame`, we need to
remove the default value for the fifth parameter to avoid ambiguity.

In particular:
* Always handle meta viewport in RDM. This fixes bug 1625999 too by
making touch simulation enabled and disabled consistent.
* Restore the resolution to 1 when toggling RDM. This is just simpler,
and we're not keeping around the visual viewport offsets anyways
so...
* Deal with the change more easily, at the same point we switch
scrollbars etc.

This patch modifies the behaviour of loads when the DONT_RETARGET
nsIURILoader flag is set, making them ignore the Content-Disposition
header. This means that loads which cannot trigger downloads will
attempt to display handleable content which would otherwise be
downloaded.
This keeps overall behaviour of object/embed elements more similar to
their behaviour pre-Fission, while allowing them to load attachment PDFs
and Images as-if they were being displayed by a plugin.
This patch does not change the existing behaviour around
unknown/unhandleable resource types in object/embed elements.
In Gecko, object/embed elements are prevented from triggering downloads
or external protocol handlers during their initial load. Other browser
engines can trigger a download for an unknown resource type (or
sometimes an attachment resource).
The new pref dom.navigation.object_embed.allow_retargeting can be
enabled to instead trigger a download when loading these resources
within an object/embed element.

This is somewhat complex, untested, never shipped, and predates
fission.
Remove it to simplify the code.

This patch removes the old docshell timeline and timeline markers codebase and replaces them with equivalent Gecko profiler marker. This patch also fixes Bug 1834143, which is a subset of 1421651.

Sorry this is not a particularly easy patch to review. But it should be
mostly straight-forward.
I kept Document::Dispatch mostly for convenience, but could be
cleaned-up too / changed by SchedulerGroup::Dispatch. Similarly maybe
that can just be NS_DispatchToMainThread if we add an NS_IsMainThread
check there or something (to preserve shutdown semantics).
