RFR: JDK-8318563: GetClassFields should not use random access to field

[Alex Menkov]

FieldStream/FilteredFieldStream classes from reflectionUtils.hpp iterate class fields in the reverse order and use field indexes to access instead of forward iteration. This is performance ineffective (see [JDK-8317692](https://bugs.openjdk.org/browse/JDK-8317692) for details).
The change introduces new class FilteredJavaFieldStream as a replacement for FilteredFieldStream.
It uses the same FilteredField/FilteredFieldsMap stuff as FilteredJavaFieldStream does.

FieldStream/FilteredFieldStream are still used by heap walking API, will be cleaned by [JDK-8317636](https://bugs.openjdk.org/browse/JDK-8317636)

Testing:
- tier1..3
- all tests which calls GetClassFields: open/test/hotspot/jtreg/serviceability/jvmti,open/test/hotspot/jtreg/vmTestbase/nsk/jvmti/GetClassFields,open/test/hotspot/jtreg/vmTestbase/nsk/jvmti/IterateThroughHeap,open/test/hotspot/jtreg/vmTestbase/nsk/jvmti/unit/IsSynthetic
including
  - test/hotspot/jtreg/vmTestbase/nsk/jvmti/GetClassFields/getclfld007.java - tests that GetClassFields returns fields in correct order;
  - test/hotspot/jtreg/serviceability/jvmti/GetClassFields/FilteredFields/FilteredFieldsTest.java - test that GetClassFields filters out field like reflection.
