PresShell::EventHandler::HandleEventWithCurrentEventInfo is the only possible
place will do such handling; other places pass either a nullptr or a
non-MouseDown/Up event.

With desktop zooming, we need to separate the concepts of "may have a distinct
visual viewport" from "has mobile viewport sizing logic applied to it".
This can be thought of as completing the disentanglement of zooming from meta
viewport support started in bug 1459260.

gfxPrefs Live preferences are almost identical to StaticPrefs.
We leave aside for now those that set a custom change callback as this feature isn't yet supported in StaticPrefs.

I think these should hold, everything that runs under them should just schedule
other stuff to some later date:
* Synth mouse events -> scheduled as refresh driver observers.
* Scroll events -> Scheduled as well.
* Caret state change events -> Also scheduled after last patch.
* IME and accessibility stuff -> I don't think they can reenter layout.
We can always revert this if it causes troubles, plus it shouldn't crash on
release so should be fine.

ScrollToShowRect already considers that possibility, so not doing it on the
caller is a bug.
Ideally scroll observers shouldn't be able to run script, more to that in a
second.

Unfortunately, `EventChainVisitor` does not grab the `nsPresContext` with
`RefPtr` by itself. Therefore, there is no guarantee of the lifetime without
checking the origin when its subclasses are instantiated. This patch changes
it and subclasses to `MOZ_STACK_CLASS` since only `EventDispatcher::Dispatch()`
creates them in the stack with given `nsPresContext`. Additionally, it's
already been marked as MOZ_CAN_RUN_SCRIPT_BOUNDARY`. Therefore, the
`nsPresContext` instance has already been guaranteed its lifetime by the
caller. For making this fact stronger, this patch marks their constructors
as `MOZ_CAN_RUN_SCRIPT`. Therefore, nobody can create those instances without
guaranteeing the lifetime of `nsPresContext` and `dom::Event`. Note that
it may look like that `mPresContext` of `EventChainPostVisitor` is not
guaranteed. However, `EventChainPreVisitor` which gives `nsPresContext` to it
is also a stack only class. So, it won't be deleted before
`EventChainPostVisitor` instance.

Additionally, this sorts out the order of member variables for minimizing the
instance size.
And also this changes `enum RenderFlags` to `enum class RenderingStateFlags`.

`CapturingContentInfo` struct is used only in `PresShell.cpp` so that we can
make it a private struct of `PresShell` if we move all users of them,
i.e., API to access them, from `nsIPresShell` to `PresShell`.

`nsIPresShell::ScrollAxis` can be used anywhere and it's used by some
utils actually. So, it should be in `mozilla` namespace and perhaps,
`PresShellForwards.h` is a good place to move it rather than creating
new header file.

There is the following usage of nsIPresShell:
```
nsCOMPtr<nsIPresShell> presShell = do_QueryReferent(mPresShellWeak);
```
So, for changing this to:
```
RefPtr<PresShell> presShell = do_QueryReferent(mPresShellWeak);
```
PresShell should have its own IID.

The fixes a latent bug with WebRender where we would clear it after reading it
in ComputeScrollMetadata, but WR would sometimes call ComputeScrollMetadata a
second time for the same scroll frame in the same transaction, resulting in
the update sometimes not making it into the transaction.

They should be CamelCase, and that's what most of them already do. This converts
the rest, which are a few.
For the ones that already used `e` or `k` prefixes, I've mostly done:
for file in $(rg Type::e layout | cut -d : -f 1 | sort | uniq); do sed -i 's#Type::e#Type::#g' $file; done
For the ones that used uppercase, I've removed the prefix if it was already in
the type name, and turn them into CamelCase.
Depends on D28680
