IndexedDB: Implement IDBIndex::getAllRecords() behind flag
This change is very similar to the IDBObjectStore::getAllRecords()
implementation found here:
https://chromium-review.googlesource.com/c/chromium/src/+/5911615
The IDBIndex version of getAllRecords() provides the index key
for the IDBRecord::key attribute. For testing, adds
idbindex_getAllRecords.tentative.any.js, which forks the existing
IDBIndex::getAll() test, but adds new test cases for direction and
large values. This change updates support-get-all.js to include
common utility and setup code shared between the IDBIndex WPT's
for getAll(), getAllKeys(), and getAllRecords().
