As part of this ticket, modify TextSearchPredicate to support $encStrEndsWith. 

End to end testing will not be done as part of this ticket.

Goals for this task:

• Leave stub for TextSearchPredicate::generateTags(). generateTags() will be implemented in a follow-up item once FLE2FindTextPayload is delivered.
• Register TextSearchPredicate as the rewriter for ExpressionEncStrEndsWith
• Make sure match expression methods of TextSearchPredicate throw an error, since match expressions for $encStrEndsWith are not supported, only aggregate expressions versions are supported.

Testing:

• Take a look at the way unit testing was done for other predicates in query_rewriter_test.cpp. We will follow a similar approach, which should allow us to unit test everything except generateTags(). generateTags() will be tested as part of the end to end testing effort.
• Make sure we add unit tests which ensure we don't rewrite the expression when we force a collection scan (look at 
  EqualityPredicateCollScanRewriteTest).
