[GCP] Billing dashboard fixes

[endorama]

What does this PR do?

• update GCP Billing Overview dashboard to 8.6.0 format
• use last_value for total billing cost instead of sum, as GCP data is already an aggregation
• add filter for event.dataset: gcp.billing
• replace filters with controls

Checklist

• I have reviewed tips for building integrations and this pull request is aligned with them.
• I have verified that all data streams collect metrics or logs.
• I have added an entry to my package's changelog.yml file.
• I have verified that Kibana version constraints are current according to guidelines.

Hi! We just realized that we haven't looked into this PR in a while. We're sorry! We're labeling this issue as Stale to make it hit our filters and make sure we get back to it as soon as possible. In the meantime, it'd be extremely helpful if you could take a look at it as well and confirm its relevance. A simple comment with a nice emoji will be enough :+1. Thank you for your contribution!
