[iOS] Remove max depth parameter while measuring layout of shadow view

[dratwas]

Summary

Searching for the ancestor view while measuring a shadow view layout relative to the ancestor is limited to 30. I couldn't find the reason nor commit where it was introduced (because I have no access to internal facebook commits).
I think we should keep looking for an ancestor view until the shadow view has the superview property.

Changelog

[iOS] [Fixed] - Remove maximum searching depth while measuring layout.

Test Plan

• Tested if RNTester works as expected.
• Tested in app with a lot of nested flatlists where sometimes I was facing this redbox because of the max depth limit.
