Bug 28371: Passpreviously fetched branches and itemtypes through and fetch all needed AV at once

This patch updates the searchResuls code to pass through the pre-constructed branches and itemtype lookups
to XSLTParse4Display to avoid repeating this

It also updates getAuthorisedValues4MARCSubfields to fetch the values for mapped subfields and pass
then through to transforMarc4XSLT

Note that we currently blank invalid branches and itemtypes - I presrve this, we should open another bug
if we want to change this behaviour

Changes are covered by tests

To test:
1 - Perform searches in OPAC and staff client that return many records
2 - Use the 'Network' tab on the browser console (opened with F12 usually) to see the time taken
3 - Note the speed before the patch
4 - Apply patch
5 - restart all the things
6 - Note improvement in speed

**Note: The improvement is more drastic the more items per record, try adding large numbers of items to your search results to test**
