We previously (in bug 1491235) adjusted some utility code to make
layout-contained frames behave as if they have no baseline.
But that's not sufficient. To make frames fully report lack-of-a-baseline,
we now do the following for layout-contained frames, as of this patch:
(a) We now leave the ReflowOutput outparam's BlockStartAscent member at its
default value (which is what we do for frames without a baseline like
e.g. nsCheckboxRadioFrame and nsHTMLCanvasFrame). And if the parent cares
about the baseline, it'll then ask directly, using a baseline getter.
(b) We now return 'false' in more implementations of bool-returning
baseline-getter-methods (where 'false' indicates 'no baseline').
(c) We now return the margin-box-bottom edge, in the nscoord-returning
'GetLogicalBaseline()' getter method. (We typically do this by deferring
to the inherited method, which ultimately comes from nsFrame's
implementation). It's appropriate to use the margin-box-bottom edge when
there's no baseline, per the definition of 'vertical-align: baseline',

Per the discussion in:
https://groups.google.com/d/msg/mozilla.dev.platform/P79pwa9z5m8/iPYPAWPHCAAJ
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.

This patch moves some `enum` in `nsIPresShell` which are in public scope into
`mozilla` namespace and change them as `enum class`es.
Unfortunately, only "where to scroll" enum is just defines constants of
percentages of scroll destination. Therefore, this patch makes only them
as `static const`.

Additionally, this patch makes `nsFrame.h` stop including `nsIPresShell.h`
and makes each users include `mozilla/PresShell.h` instead. So, this improves
rebuild performance of `nsIPresShell.h` (and `mozilla/PresShell.h` in the
future).
Note that due to `nsIFrame::PresShell()`, `mozilla::` prefix is necessary for
`PresShell` in a lot of classes which are derived from `nsIFrame` even in
`.cpp` files.

Except retrieving from weak reference, `nsIFrame` should treat
`mozilla::PresShell` directly rather than via `nsIPresShell`.

`nsPresContext` should use `mozilla::PresShell` directly instead of
`nsIPresShell`. This patch makes it.
Unfortunately, `nsPresContext` and `nsIFrame` have `PresShell()`. Therefore,
we cannot use `PresShell*` in its methods so that this patch uses `mozilla::`
namespace prefix.
It might be better to rename them as `PresShellPtr()` in another bug.

This is more consistent with what the Rust bits of the style system do, and
removes a pointer from ComputedStyle which is always nice.
This also aligns the Rust bits with the C++ bits re. not treating xul pseudos as
anonymous boxes. See the comment in nsTreeStyleCache.cpp regarding those.
Can't wait for XUL trees to die.

Really sorry for the size of the patch :(
Only intentional behavior change is in the uses of HasLengthAndPercentage(),
where it's easier to do the right thing. The checks that used to check for
(IsCalcUnit() && CalcHasPercentage()) are wrong since bug 957915.

Also for the intersection observer root margin, since it was easier to fix it
up and clean it up than not doing it.
This is the first big step to get rid of nscoord. It duplicates a bit of logic
in nsLayoutUtils since for now max/min-width/height are still represented with
nsStyleCoord, but I think I prefer to land this incrementally.
I didn't add helpers for the physical accessors of the style rect sides that
nsStyleSides has (top/bottom/left/right) since I think we generally should
encourage the logical versions, but let me know if you want me to do that.

For elements that have box-sizing:border-box specified, the aspect ratio
calculation code subtracts out border & padding from any specified property
values.
So, when we create a fake "override" specified property value for a flex item
whose main size has been resolved, we need to add in the border and padding to
account for the fact that they're going to be subtracted out later.

Keywords on the sizing properties in the block axis should behave as
initial values in the flex frame. We store the keywords as enum, instead
of auto or none in nsStyleCoord, so we have to handle it explicitly.

This patch basically reverts the functional part of changeset 52bd865d757c.
I'd optimistically hoped we could skip this early-freeze in order to compute &
report a bit more "potential flexing" information via devtools. Bbut it turns
out that breaks assertions & produces bogus information for flex items whose
base size vs. min/max-clamped "hypothetical" sizes are very
different. (Specifically: it produces nonsense for flex items whose base sizes,
if unclamped, would reverse the directionality of flexing.)

This patch also updates the expectations in the mochitest test_flex_items.html.
Before this commit, the test (incorrectly) expected the mainBaseSize API to
return some items' *final sizes*, because that's what our implementation did
return, up until now. As of this patch, that API will now return the item's
actual flex base size, which means the text expectations need to change.
I'm also adding a new flex item to the test, to exercise a formerly-untested
scenario. And to accommodate this new item, I'm also doubling the width of
the flex container to be sure there's plenty of space.
