feat(bigquery): implement custom minute time grains

[villebro]

SUMMARY

Currently the BigQuery engine spec only supports full seconds/minutes/hours due to the dialect not natively supporting custom intervals. This PR adds support for the missing default 5, 10, 15 and 30 min grains by utilizing some custom timestamp handling functions:

Tested manually - ok :) I had only problem with connection to physical table (not from sql editor). But time columns mentioned in description worked. 🟢
