Move serverless pipeline definitions to separate files (#187253)

## Summary

This PR moves the definitions of the following pipelines from
`catalog-info.yaml` to `.buildkite/pipeline-resource-definitions`:
- `buildkite-pipeline-kibana-emergency-release` ->
`.buildkite/pipeline-resource-definitions/kibana-serverless-emergency-release.yml`
- `kibana-tests-pipeline` ->
`.buildkite/pipeline-resource-definitions/kibana-serverless-quality-gates.yml`

More details in the original PR #186833, which is split into the
creation of the new pipeline (#187251) and moving existing pipelines
from catalog-info.yaml to .buildkite/pipeline-resource-definitions (this
PR).

 # Please avoid creating new kibana pipelines in this file to avoid bloating.
 # Instead, create a new file in the pipeline-resource-definitions directory, and wire it in through the locations.yml file.
