Add prefixsubject change query operator

Often subjects have a prefix, e.g. a bug ID in square brackets.
Searching changes by such prefixes is currently not possible since the
current subject query operator is doing a full text search that ignores
special characters such as square brackets. To address this add another
prefixsubject operator for prefix searches. This is consistent with the
existing prefixhashtag and prefixtopic operators which allow prefix
searches for hashtags and topics.

Bug: Google b/153611998
Release-Notes: added prefixsubject index field, requires index upgrade
