SERVER-101122 implements the required query analysis changes, however, it only provides unit tests for verification.

As part of this ticket, introduce js integration tests to verify query analysis replaces payloads as expected for $encStrStartsWith.

Things to consider:

• We will ultimately want to run tests against all supported commands (i.e Find, Agg, Count, Distinct, FindAndModify, Update & Delete).
• Look at other tests in fle2_query_analysis/ to see how they perform testing.
• Consider adding a new file (i.e encTextSearch.js) which specifically tests scenarios that should not throw errors, and verifies that the constant literals have been replaced with the bindata placeholders.
• Consider introducing a test runner that can be configured to run against all commands, which we can reuse to test remaining expressions later on.
• Consider adding a separate file (i.e encTextSearch_errors.js) which specifically checks for errors we expect query analysis to throw when $encStrStartsWith is used incorrectly.
• We can also combine the error/non error cases into a single file. Look at fle_agg_lookup_multi_schema.js to see how we use the testData object to configure tests.
