Add Neon-Batch- headers to OPTIONS response for SQL-over-HTTP requests (#6116)

Browse Source 
This is needed to allow use of batch queries from browsers.

## Problem

SQL-over-HTTP batch queries fail from web browsers because the relevant
headers, `Neon-Batch-isolation-Level` and `Neon-Batch-Read-Only`, are
not included in the server's OPTIONS response. I think we simply forgot
to add them when implementing the batch query feature.

## Summary of changes

Added `Neon-Batch-Isolation-Level` and `Neon-Batch-Read-Only` to the
OPTIONS response.
