### What changes were proposed in this pull request?
This PR is a followup of https://github.com/apache/spark/pull/30504. It proposes:
- Rename `NoSideEffect` to `NoThrow`, and use `Expression.deterministic` together where it is used.
- Clarify, in the docs in the expressions, that it means they don't throw exceptions
### Why are the changes needed?
`NoSideEffect` virtually means that `Expression.eval` does not throw an exception, and the expressions are deterministic.
It's best to be explicit so `NoThrow` was proposed - I looked if there's a similar name to represent this concept and borrowed the name of [nothrow](https://clang.llvm.org/docs/AttributeReference.html#nothrow).
For determinism, we already have a way to note it under `Expression.deterministic`.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Manually ran the existing unittests written.
Closes#30570 from HyukjinKwon/SPARK-33544.
