Fix Endpoint StringArray Parameter + operationContextParams issues

Fix Endpoint StringArray Parameter + operationContextParams issues

Motivation and Context

There are a few issues in our implementations of StringArray type Endpoint Parameters and the various bindings:

• Incomplete support for parsing chained index expressions
• incomplete support for MultiSelect lists - both in parsing and in generating acceptor code.
• incorrect logic for including JmesPathRuntime
• StaticContextParams with stringarrays are not handled.

Note: The first two of these apply to general JmesPath support and improve support for Waiters as well as endpoints.

Modifications

• Add the Smithy Standard string-array test model and a complete suite of tests for the bindings defined there. This is the standard test suite that caught the above issues.
• Add support for parsing chainged index expressions w/ multi-select lists
• Add support generating acceptor code for multiselect lists
• Add support for StaticContextParams with StringArrays
• Fix logic used to determine if we include JmesPathRuntime

Testing

• Added standard smithy string-array test model + suite
• New JmesPath parser and acceptor generator tests.
