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.

Gentest tests started failing because Chrome changed behavior of overflowed align-content container. Spec says should fallback to "safe center", which is really just "start", instead of previous "center" behavior. This changes behavior accordingly.
There is one bit where I think we are doing the wrong thing wrt alignment of flex start vs start (which we don't support yet), but couldn't repro a failing chrome test.

D52087013 (#1513) fixed some issues, including where measuring under max-content or fit-content, align-content stretch would consume the entire available cross-dimensions, instead of only sizing to definite dimension, like the spec dicates.
I missed a case, where flexbox considers a container as having a definite cross-size if it is being stretched, even if it doesn't have a definite length.
https://www.w3.org/TR/css-flexbox-1/#definite-sizes
> 3. Once the cross size of a flex line has been determined, items in auto-sized flex containers are also considered definite for the purpose of layout;
> 1. If a single-line flex container has a definite cross size, the outer cross size of any stretched flex items is the flex container’s inner cross size (clamped to the flex item’s min and max cross size) and is considered definite.
We handle `align-items: stretch` of a flex container after cross-size determination by laying out the child under stretch-fit (previously YGMeasureModeExactly) constraint. This checks that case, and sizing the line container to specified cross-dim if we are told to stretch to it.
We could probably afford to merge this a bit with later with what is currently step 9, where we end up redoing some of this same math.

Fixes https://github.com/facebook/yoga/issues/1300
Fixes https://github.com/facebook/yoga/issues/1008
This fixes a smattering of issues related to both sizing and aligment of multi-line-containers:
1. We were previously incorrectly bounding the size of each flex line to the min/max of the entire container.
2. Per-line leads were sometimes incorrectly contributing to alignment within the line
3. The cross dim size used for multi-line alignment is not correct, or correctly clamped. If the available size comes from a max constraint, that was incorrectly used instead of a definite size, or size of content. Leads were entirely skipped for min constraint.
Need to test how breaking this is, to see if it might need to go behind an errata.

### Changes made
- Regenerated tests (as some aspect ratio tests seem to be out of date compared to the fixtures)
- Added SpaceEvenly variant to the "Align" enums (via enums.py)
- Implemented `align-content: space-evenly` alignment in CalculateLayout.cpp
- Added generated tests `align-content: space-evenly`
- Updated NumericBitfield test to account for the fact that the Align enum now requires more bits (this bit could do with being reviewed as I am not 100% certain that it's valid to just update the test like this).
### Changes not made
- Any attempt to improve the spec-compliance of content alignment in general (e.g. I think https://github.com/facebook/yoga/pull/1013 probably still needs to happen)

Summary: This is an update of facebook/yoga#368 which was reverted. It fixes support for align-content: strech with multiple lines. The problem with the last attempt at solving this was that align-items:stretch was interfering. We handle this now by detecting when the flex basis of the children hints at them overflowing. This is not 100% correct as the size of the items could change when remeasuring but it will work in 99% of cases.

Summary:
Fixes ```align-content:strech``` on nodes without specified cross dimension, if there are multiple lines. Currently it uses the full height of the parent, but it has to use the line height. As we don't know the number of lines until here, we need to realign the relevant children.
