Cleanup/Perf: Float32Array/Float64Array removal (#5877)

## Summary

Redoing https://github.com/Comfy-Org/ComfyUI_frontend/pull/5567, without
the link rendering changes.

## Changes

- **What**: Standardizing the Point/Size/Rect logic around numeric
tuples instead of typed arrays.

## Review Focus

Cutting here and going to continue in a second PR.

Do the simpler types make sense?
Do we want to keep the behavior of Rectangle as it is now?
