remove import cycle and needless exports around eventLogger
Created by: sqs
Moved 2 functions (pageViewQueryParameters and
handleQueryEvents) from
analyticsUtils.tsxto
eventLogger.ts` because they were only used in the latter.
This also removes an import cycle that messed up esbuild. (Perhaps esbuild's behavior is buggy here, but either way, this is a good change because it removes needless export API surface.)
