This pull request addresses the issue where combining align-content and align-items properties resulted in incorrect layout behavior in Yoga version 3.1.0, as reported in [Issue https://github.com/facebook/yoga/issues/1739](https://github.com/facebook/yoga/issues/1739).
# Changes Made:
Alignment Logic Update: Modified the alignment calculations to ensure that the combination of align-content and align-items properties produces the expected layout, consistent with CSS Flexbox standards and previous Yoga versions.
Test Cases Added: Introduced new test cases to cover scenarios involving various combinations of align-content and align-items properties to prevent future regressions.
# Testing:
All existing tests pass successfully.
New test cases confirm that the layout behaves as expected when align-content and align-items are used together.
# Impact:
This fix ensures that layouts using both align-content and align-items properties render correctly, aligning with the behavior observed in Yoga version 1.19.0 and standard web browsers.

Chrome made some changes for how overflowed row-reverse containers are laid out which was causing some issues on CI. I updated them here and skipped the new failing tests which we would want to followup on.
For LTR, the differences are seen below

The extra space is now extending past the flex start edge vs flex end. RTL is the opposite. NickGerleman had deviated from the spec back in the day to match Chrome and it seems they made the adjustment recently. T208209388 is tracking the followup to align with the spec again. Basically, there is a notion of fallback alignment when certain justification/alignment values cannot actually apply. Right now we are falling back to flex start in all cases but we should fallback to start sometimes.

Adds gentest support for intrinsic sizing keywords and creates an initial batch of somewhat interesting tests for these keywords on `width`, `height`, `min-width`, `min-height`, `max-width`, `max-height`, and `flex-basis`

This PR adds support for `display: contents` style by effectively skipping nodes with `display: contents` set during layout.
This required changes in the logic related to children traversal - before this PR a node would be always laid out in the context of its direct parent. After this PR that assumption is no longer true - `display: contents` allows nodes to be skipped, i.e.:
```html
<div id="node1">
<div id="node2" style="display: contents;">
<div id="node3" />
</div>
</div>
```
`node3` will be laid out as if it were a child of `node1`.
Because of this, iterating over direct children of a node is no longer correct to achieve the correct layout. This PR introduces `LayoutableChildren::Iterator` which can traverse the subtree of a given node in a way that nodes with `display: contents` are replaced with their concrete children.

```
would be laid out as if the green nodes (ones with `display: contents`) did not exist. It also changes the logic where children were accessed by index to use the iterator instead as random access would be non-trivial to implement and it's not really necessary - the iteration was always sequential and indices were only used as boundaries.
There's one place where knowledge of layoutable children is required to calculate the gap. An optimization for this is for a node to keep a counter of how many `display: contents` nodes are its children. If there are none, a short path of just returning the size of the children vector can be taken, otherwise it needs to iterate over layoutable children and count them, since the structure may be complex.
One more major change this PR introduces is `cleanupContentsNodesRecursively`. Since nodes with `display: contents` would be entirely skipped during the layout pass, they would keep previous metrics, would be kept as dirty, and, in the case of nested `contents` nodes, would not be cloned, breaking `doesOwn` relation. All of this is handled in the new method which clones `contents` nodes recursively, sets empty layout, and marks them as clean and having a new layout so that it can be used on the React Native side.

Right now there is no way to test fixtures with `auto` widths, heights, or flex basis - even though we expose those functions. I updated gentest to generate those functions. Notably, position and margin (the other auto-able props) already account for this.
I also created `YGAutoTest.html` to test this. Not really testing the capabilities of `auto` here, just if we can create a test about it.

Content box impl had a bug where we resolved padding % against the same reference length as the dimensions. Padding should always be against containing block's width. This is also true for width, but not for height, which should be against containing block's height.
This just pipes the width into our box sizing functions.

box sizing is really just a reinterpretation of what length properties (like `width`, `height`, `max-width`, etc) mean. So to implement this I just add the border and padding if we are in content box when we ask for any of these properties. All the math that gets done by the algorithm is still in border box land, and the layout we return is to be interpreted as the border box (this is actually the expected behavior per https://drafts.csswg.org/css-sizing/#box-sizing). This makes this implementation pretty simple actually.

We do not validate the aspect ratio to ensure it is non zero and non inf in a lot of places. Per the spec, these values should act like auto. There is no auto keyword, but it is the default so I just set the style to a default FloatOptional in this case
