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.

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.

It's a rather useless interface:
* nsITextControlFrame is only implemented by nsTextControlFrame, so we
can just use that.
* nsIFormControlFrame had very few actual functionality, mostly
scattered around:
* SetFormProperty(select) was only useful for nsTextControlFrame.
* SetFormProperty(value) was only called on file controls.
* SetFocus() did mostly nothing, or things that can be done in
ElementStateChanged instead.
There are some do_QueryFrame calls that I replaced for better checks in
font inflation and nsIFrame, but I'll adjust to preserve behavior if you
insist (it just such a somewhat-random check).

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.

The removed reftsts test basically the opposite, and are sufficiently
covered by the WPTs that we start passing, so just remove them.

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

Previously, for writing-mode using central baseline alignment (i.e. `vertical-(lr|rl)`,
we simply used the center of content-box in `nsLineLayout::VerticalAlignFrames`.
However, this is incorrect for e.g. a `div` with two lines of text - just like how
its alphabetical baseline is the baseline of the second line of text, the central
baseline should be the centerline of the second line.

Before, there existed 3 virtual functions that calculated baselines:
- `GetLogicalBaseline`
- `GetVerticalAlignBaseline`
- `GetNaturalBaselineBOffset`
Each of them had slightly different behaviours:
- `GetLogicalBaseline` would synthesize a baseline if there is no baseline.
Others would simply return `false`.
- `GetNaturalBaselineBOffset` requires the caller to pick which of first/last
baseline to calculate. Others pick on on their own.
- `GetNaturalBaselineBOffset`'s result can be either offset from border box
start/end edge, depending on the caller-supplied baseline. Others always
return offset from border box start edge.
Now:
- `GetNaturalBaselineBOffset` is the sole virtual function.
- `GetLogicalBaseline` exists to support its use, with 2 virtual helper functions:
- `SynthesizeFallbackBaseline` to generate a baseline for elements that
doesn't have one.
- `GetBaselineSharingGroup` to preserve the default baseline picking behaviour.

In the description of the mTruncated bit, its purpose is the same as calling
SetInlineLineBreakBeforeAndReset(). We've removed all its usages in previous
patches, so the bit is no longer needed.

This matches closer what Chrome and Safari do (Safari paints outside of
the box when this happens, but the layout box still respects the
author), see:
data:text/html,<button style="padding: 0; width: 0">
data:text/html,<input type=checkbox style="width: 0">
Etc. For checkboxes, this matches what OSX does, too.
Since we still want checkboxes to be slightly larger than what they'd be
otherwise, we add a hook to tweak it when non-native theme is enabled.

This patch adds the struct as a parameter to various functions.
The struct is cached in ReflowInput so that we don't need to pass it
down to the internal method where nsIFrame::ComputeSize() is called.
In the subsequent patches, we'll use it to revise the implementation of
flex container's flex base size resolution, and size overrides.
