Title: Make simple_query_string leniency more fine-grained

Previously, the leniency was on a per-query basis, with each query being
parsed into multiple queries, one for each field. If any one of these
queries failed, the entire query was discarded in the name of being
lenient.

Now query parts will only be discarded if they fail for a particular
field, the entire query is not discarded. This helps when performing a
query over a numeric and string field, as only the sub-queries that are
invalid due to format exceptions will be discarded.

Also moves the `simple_query_string` queries out of SimpleQueryTests and
into a dedicated SimpleQueryStringTests class.

Fixes #7967
