Support custom gcs location for bigquery read

[damccorm]

Java and Python handles the usage of temp location for bigquery io differently.
Java's Read only uses and validates tempLocation but Write takes customGcsLocation and falls back to tempLocation.
Python's Read takes gcs_location and falls back to temp_location while Write takes custom_gcs_temp_location and falls back to temp_location.

We need an equivalence of

beam/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/BigQueryIO.java

Line 2314 in 0a0399f

public Write<T> withCustomGcsTempLocation(ValueProvider<String> customGcsTempLocation) {

for the Read class.
