[GCP] Migrate compute metrics dashboard to lens

[tommyers-elastic]

What does this PR do?

Migrates GCP compute metrics dashboard visualizations to lens. Adds top-level datastream filter to improve performance.

Note to reviewers: when migrating the 'Read/Write IO' and "Network sent/received' panels, I noticed that the existing aggregations are based on doc count, not top values of the metric. I thought this was a bit strange. The resulting charts are quite different, as you can see in the screenshots below. One additional change in the new panels, is that I have left the 'Other' groupings in the 'top values' aggs, which can be removed if deemed necessary.

I installed the package in this PR but the dashboard does not seem to be updated, I still see the "Before" version. @tommyers-elastic do you have any suggestion? I started from scratch with a 8.6.0 stack started through elastic-package.

Overall the dashboard looks good and works as expected. 2 minor comments:

• it seems this PR builds upon [GCP] Remove broken input control reference panel and replace with new-style control #5032
• tags (that have been exported through elastic-package) should not be added

I tested the dashboard with data, the data stream filter is applied, seems fine to me!
