Henry Q. Dineen fe813143e2 [compiler] Check TSAsExpression and TSNonNullExpression reorderability (#33788 )

## Summary

The `TSAsExpression` and `TSNonNullExpression` nodes are supported by
`lowerExpression()` but `isReorderableExpression()` does not check if
they can be reordered. This PR updates `isReorderableExpression()` to
handle these two node types by adding cases that fall through to the
existing `TypeCastExpression` case.

We ran `react-compiler-healthcheck` at scale on several of our repos and
found dozens of `` (BuildHIR::node.lowerReorderableExpression)
Expression type `TSAsExpression` cannot be safely reordered`` errors and
a handful for `TSNonNullExpression`.


## How did you test this change?

In this case I added two fixture tests

React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.

This package contains the React Compiler Babel plugin use in projects that make use of Babel. You can find instructions for using this plugin here: https://react.dev/learn/react-compiler
