[ska] [xpack] relocate platform tests (#225223)

## Summary

Part of https://github.com/elastic/kibana-team/issues/1503

This PR is mostly about moving platform tests from x-pack/test/

Before:

```
x-pack/test/
     | - ftr_apis/
     | - load/
     | - plugin_api_perf/
     | - fleet_packages/
     | - fleet_tasks/
     | - scalability/
     | - task_manager_claimer_update_by_query/
```

After: 
```
x-pack/platform/test/
     | - ftr_apis/
     | - load/
     | - plugin_api_perf/
     | - fleet_packages/
     | - fleet_tasks/
     | - scalability/
     | - task_manager_claimer_update_by_query/

 ## Overview
+
 It is important to test individual API endpoint for the baseline performance, scalability, or breaking point. If an API doesn’t meet performance requirements, it is a bottleneck.
 This capacity tests track how response time changes while we slowly increase number of concurrent requests per second.
 While using similar load model, we are able to identify how many requests per second each endpoint can hold with response time staying below critical threshold.

 Capacity API test defines 3 response time thresholds (default ones: 3000, 6000, 12000) in ms. Test results report rps (requests per second) for each threshold.

 ## Method
 1. You need two cloned repos of Kibana, so clone a second Kibana of your personal form along side your existing clone. Personally I have two co-located Kibana folders (`./elastic/kibana` and `./elastic/_kibana`, where the first is my working clone and the other is never used for actual dev work, but that's just me -GM).
-1. You can run the FTS in the main clone of your fork by running `node scripts/functional_tests_server.js --config=test/plugin_api_perf/config.js` in the `x-pack` folder.
+1. You can run the FTS in the main clone of your fork by running `node scripts/functional_tests_server.js --config=platform/test/plugin_api_perf/config.js` in the `x-pack` folder.
 1. Once you've began running the default FTS, you want your second FTS to run such that it is referencing the Elasticsearch instance started by that first FTS. You achieve this by exporting a `TEST_ES_URL` Environment variable that points at it. By default, you should be able to run this: `export TEST_ES_URL=http://elastic:changeme@localhost:9220`. Do this in a terminal window opened in your **second** clone of Kibana (in my case, the `./elastic/_kibana` folder).
 1. One issue I encountered with FTS is that I can't tell it _not to start its own ES instance at all_. To achieve this, in `src/platform/packages/shared/kbn-test/src/functional_tests/tasks.js` you need to comment out the line that starts up its own ES (`const es = await runElasticsearch({ config, options: opts });` [line 85]  and `await es.cleanup();` shortly after)
 1. Next you want each instance of Kibana to run with its own UUID as that is used to identify each Kibana's owned tasks. In the file `x-pack/test/functional/config.base.js` simple change the uuid on the line `--server.uuid=` into any random UUID.
-1. Now that you've made these changes you can kick off your second Kibana FTS by running ths following in the second clone's `x-pack` folder: `TEST_KIBANA_PORT=5621 node scripts/functional_tests_server.js --config=test/plugin_api_perf/config.js`. This runs Kibana on a different port than the first FTS (`5621` instead of `5620`).
