This makes `Document::GetShell()` return `PresShell*` instead of `nsIPresShell`.
Additonally, "shell" is unclear ("docshell" vs. "presshell"). Therefore, this
also renames `Document::GetShell()` to `Document::GetPresShell()`.
Similarly, some other method names of `Document` are also renamed from
`*Shell*` to `*PresShell*`.

This can happen, for example, when GetAccessibleOrContainer is called within SelectionManager::ProcessSelectionChanged due to focusing a direct child of a shadow root.
In this case, the common ancestor is the shadow root itself.
Previously, we returned null in this case because GetFlattenedTreeParent doesn't work on the shadow root itself.
Now, we check if the given node is the shadow root, and if so, we use the shadow host instead.
This prevents the "We must reach document accessible implementing text interface!" assertion in SelectionManager::ProcessSelectionChanged when a direct child of a shadow root gets focus.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
The issue was specific to content insertion directly under a shadow root, the
rest should work (see bug 1427825 for the fix for other similar occurrences).
The removal of the aContainer argument follows the same pattern as bug 1442207.

This can easily be reproduced if the ancestor being owned has role="presentation", but there are other cases as well.
If we don't prevent this, we end up with a loop.

This condition is rare and does indicate a problem which breaks accessibility.
However, we aren't getting any closer to diagnosing this as a result of this crash, so it causes user pain without any gain to us.

Gecko has two document roles: roles::DOCUMENT_FRAME and roles::DOCUMENT.
However, the former was not being used at all; the latter was being used
for both ARIA documents and for the native document container. We can
therefore fix this issue by repurposing the unused internal role:
* Rename the role from roles::DOCUMENT_FRAME to roles::NON_NATIVE_DOCUMENT,
and add clarification to the doc strings in Role.h
* Ensure load events are still emitted for ARIA documents (bug 759833)
* Update the ARIA-document mochitests to reflect the above changes
* Change the ATK role mapping for roles::DOCUMENT (the native container)
from ATK_ROLE_DOCUMENT_FRAME TO ATK_ROLE_DOCUMENT_WEB.
* On IAccessible2, map roles::NON_NATIVE_DOCUMENT to ROLE_SYSTEM_DOCUMENT.
This should cause there to be no change in behavior for that platform.
* On macOS map roles::NON_NATIVE_DOCUMENT to NSAccessibilityGroupRole
with a subrole of AXDocument.
