[ObsUX][APM] Migrate APM infra tests to agnostic deployment tests (el…

…astic#199775)

### Summary
Closes elastic#198976
Part of elastic#193245

This PR contains the changes to migrate infrastructure test folder to
Deployment-agnostic testing strategy.

#### How to test
Serverless
```
node scripts/functional_tests_server --config x-pack/test/api_integration/deployment_agnostic/configs/serverless/oblt.serverless.config.ts
node scripts/functional_test_runner --config x-pack/test/api_integration/deployment_agnostic/configs/serverless/oblt.serverless.config.ts --grep="APM"
```
It's recommended to be run against
[MKI](https://github.com/crespocarlos/kibana/blob/main/x-pack/test_serverless/README.md#run-tests-on-mki)

Stateful
```
node scripts/functional_tests_server --config x-pack/test/api_integration/deployment_agnostic/configs/stateful/oblt.stateful.config.ts
node scripts/functional_test_runner --config x-pack/test/api_integration/deployment_agnostic/configs/stateful/oblt.stateful.config.ts --grep="APM"
```
Checks

- [ ] (OPTIONAL, only if a test has been unskipped) Run flaky test suite
- [x]  local run for serverless
- [x]  local run for stateful
- [x]  MKI run for serverless
