Send main build metrics (#1127)

*Issue #, if available:*

*Description of changes:*
Emit a failure metric if main build fails. Since this workflow is
triggered with pushes to main or a release branch, we want to be
notified if there is a failure with the build process or e2e tests.

Tested by temporarily adding an on: push: trigger to my own branch in
this repo and testing the updated workflow. Verified that failure metric
was successfully published to cloudwatch.
