Pawel Kozlowski 9f0c549bc8 perf(ivy): avoid memory allocation in the isAnimationProp check (#32997)
Accessing a string's character at index allocates a new, single character string.
A better (faster) check is to use `charCodeAt` that doesn't trigger allocation.

This simple change speeds up the element_text_create benchmark by ~7%.
