RFR: 8346099: JFR: Query for 'jfr view' can't handle wildcard with multiple event types

[Erik Gahlin]

Could I have a review of PR that improves the query language for 'jfr view' so it can handle a wildcard with multiple event types, e.g. "SELECT * FROM E1, E2".

Every field has an index which corresponds to where it is located in resultFields array. Today, the same index can appear multiple times. See FieldBuilder::createWildcardField how this can happen when there are multiple event/filter types. The fix is to set the index after all fields have been added. 

Testing: jdk/jdk/jfr + manual check

Thanks
Erik
