[compiler] Store original and new prop names (#31440)

Previously, we'd directly store the original attributes from the jsx
expressions. But this isn't enough as we want to rename duplicate
attributes.

This PR refactors the prop collection logic to store both the original
and new names for jsx attributes in the newly outlined jsx expression.

For now, both the new and old names are the same. In the future, they
will be different when we add support for outlining expressions with
duplicate attribute names.
