Summary:
`child.offsetLeft/Top` calculates the offset from child to its nearest positioned ancestor, not its direct parent. These are often the same and have not mattered in the past since we have not supported position static. Since are are in the process of supporting that, we would like our tests to be usable so this adjusts the gentest methodology to only speak the same language as Yoga - that is left/top are always relative to direct parents.
It works by using `getBoundingClientRect().left/top` instead. Then we pass that down to children and subtract it from the childs `getBoundingClientRect()` to get the position relative to the parent. Note we have to round the final result as `child.offsetLeft/Top` is rounded.

Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1447
Just ran
```
ruby xplat/yoga/gentest/gentest.rb
```
It seems that D50453324 changed a bunch of the import directories in these test files but for some reason it did not get picked up for this test. As a result we are seeing failing github checks like https://github.com/facebook/yoga/actions/runs/6738747977/job/18318958442. Should be good now.

Summary:
Doing some test-driven-development to support this feature, so I will start by adding a ton of tests to ensure the nuance of position: static is captured in Yoga. Specifically I have a slew of tests to capture:
* Insets have no effect on static elements
* Insets are relative to the nearest non-static ancestor
* Percentage values for insets, padding, and margin of absolute children respect the correct dimension of the nearest non-static ancestor
* Also added similar ones for static and relative children which should just respect their ancestor (static only because it is a flexbox by default)
* This rule does NOT apply to border
* The containing block for absolute children is the padding box of their nearest non-static ancestor
* The containing block for static children is the content box of their parent (because all elements are flex containers in yoga, at least right now)

Summary:
I am about to embark on supporting `position: static` in Yoga. The enum exists already (and is the default position type, lol) but does not actually do anything and just behaves like `position: relative`.
My approach here is to write a bunch of tests to test for the various behaviors of static positions and then develop on Yoga afterwards to get those tests passing. To do this, we need to make a few changes to the gentest files as there is not support for adding `position: static` at the moment:
* Make it so that the gentest code can physically write `YGPositionTypeStatic` if it encounters `position: static` in the style
* Make it so that gentest.js knows that Yoga's default is actually static. This way the code generated in the tests will actually label nodes for non default values
* Explicitly label the position type even when it is not declared in the style prop (with the exception of the default)
* Regenerate all the tests
Additionally I added the first, basic test: making sure insets do nothing on a statically positioned element.
