Add getSymbols(Predicate, LookupKind) compatibility method

Add a compatibility helper method for `getSymbols(Predicate<Symbol>, LookupKind)`.

**Context:**
In [gradle-baseline](https://github.com/palantir/gradle-baseline#baseline-error-prone-checks), we maintain our own set of error-prone rules and ran into similar JDK 17 compatibility problems as mentioned in #2330.

However for our custom rules, we also need a compatibility helper for `getSymbols(Predicate, LookupKind)`. For now, we work around this by copying parts of the `ErrorProneScope` class (([PR](palantir/gradle-baseline#1936))) but ideally we could reuse the existing helper and wouldn't have to maintain our own fork of this class.

Fixes #2629
