A percentage basis is needed to resolve percentage block size when computing
children's intrinsic inline size contributions. This is necessary for a child or
descendants with a preferred aspect-ratio so that the block size can transfer
through the aspect-ratio to become an intrinsic inline size.
The change in `nsFlexContainerFrame::ComputeIntrinsicISize()` is necessary to
keep us passing
`testing/web-platform/tests/css/css-flexbox/image-nested-within-definite-column-flexbox.html`.
The change in `nsPlaceholderFrame::AddFloatToIntrinsicISizeData()` is necessary
to keep us passing
`testing/web-platform/tests/css/css-sizing/intrinsic-percent-replaced-dynamic-010.html`.
`GetISizeInfo()` in BasicTableLayoutStrategy.cpp is modified to pass table cell
frame's bsize as percentage basis. Otherwise,
`layout/reftests/bugs/522632-1.html` fails. This is our current behavior, but it
is bug 1461852.

This patch changes the signature to `GetMinISize()`, `GetPrefISize()`,
`IntrinsicISize` by adding a helper struct as a preparation. Then we can just
add more data such as a percentage basis to the struct without altering the
signature in the future.
When passing `IntrinsicSizeInput` struct down to another helper method, we
generally just pass the original one if the method is computing the intrinsic
size of our own or our anonymous children. If the method is computing our
children's intrinsic contribution, we'll need to create a brand new
`IntrinsicSizeInput` for our children.

`ColumnSetWrapperFrame` inherits from `nsBlockFrame`, which already has member
variables to cache the intrinsic inline sizes. Let's use it.

Most frame types have identical or very similar implementation for GetMinISize()
and GetPrefISize(), and many of them already have `IntrinsicISize()` to unify
the implementation. This patch introduces nsIFrame::IntrinsicISize() so that
derived classes only need to override one method.
`nsBlockFrame`, `ColumnSetWrapperFrame`, and `nsColumnSetFrame` are the only
three classes where their `GetMinISize()` and `GetPrefISize()` have significant
differences. Therefore, we rename `GetMinISize()` and `GetPrefISize()` to
`MinISize()` and `PrefISize`, respectively, and use them as helpers to implement
their `IntrinsicISize()`.
This patch doesn't change behavior.

The two macros are used in `GetPrefISize()` and `GetMinISize()` implementations.
After removing them, we could further simplify some implementations because we
don't need a `result` variable in many cases.

After D198523, NS_BLOCK_FLOAT_MGR and NS_BLOCK_MARGIN_ROOT are always
set simultaneously when initiating a frame, so we can merge them into a
single NS_BLOCK_STATIC_BFC flag. The freed bit is used to define a new
NS_BLOCK_DYNAMIC_BFC flag that has the same effect and is now used for
frames with paint/layout containment so that in D197043 they can be
updated later without having to reconstruct the frame tree. Finally
NS_BLOCK_BFC_STATE_BITS is the bitwise union of these BFC flags.
The following changes are made and cause no behavior changes:
- Instead of testing whether NS_BLOCK_FLOAT_MGR or NS_BLOCK_MARGIN_ROOT
is set, or whether all of the bits from
NS_BLOCK_FORMATTING_CONTEXT_STATE_BITS are set, we test whether any
of the NS_BLOCK_BFC_STATE_BITS is set.
- Instead of adding NS_BLOCK_FORMATTING_CONTEXT_STATE_BITS when
constructing a frame, we add NS_BLOCK_STATIC_BFC. The exception is
for frame with paint/layout containment, for which we set
NS_BLOCK_DYNAMIC_BFC instead.

Some baseline exports are context-sensitive. One example: In line-layout scenario,
the last baseline of a scroll container is always the margin-end. In other (e.g.
flex, grid) scenarios, it's the border-box clamped offset to the last line in the
container.
This enables the required 3 different behaviours for `inline-block` scroll containers
for 3 different `baseline-source` values:
- `auto`: Last baseline, margin-end
- `first`: Border-box clamped offset to the first line
- `last`: Border-box clamped offset to the last line

min-content" and "width: max-content" with column-span:all children.
There's no size containment in these tests.

mCachedPrefISize to cache intrinsic size for ColumnSetWrapperFrame, but

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.

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.

Calling nsBlockFrame::ResolveBidi() on ColumnSpanWrapperFrame may cause
nsColumnSetFrame's non-fluid continuations being converted into fluid
ones in JoinInlineAncestors().
Since ColumnSpanWrapperFrame can only have nsColumnSetFrame and
column-span wrappers kids, no need to perform bidi resolution. This
doesn't affect column contents because they'll inherit "unicode-bidi"
from ColumnSetWrapperFrame in ua.css.

I'm also adding the non-"inlines" version of the added "inlines" includes, too,
since it's nice to have them included as a pair. (It's not strictly necessary,
since in these cases we were already indirectly including the non-"inlines"
header, but it seems like a good practice.)
