[SecuritySolution] Timeline api integration tests

[angorayc]

Here are some skipped tests needed to be updated or fixed:

• x-pack/test/security_solution_api_integration/test_suites/investigation/timeline/security_and_spaces/ess/basic/events.ts
• x-pack/test/security_solution_api_integration/test_suites/investigation/timeline/security_and_spaces/ess/basic/import_timelines.ts
• x-pack/test/security_solution_api_integration/test_suites/investigation/timeline/security_and_spaces/ess/basic/install_prepackaged_timelines.ts
• x-pack/test/security_solution_api_integration/test_suites/investigation/timeline/security_and_spaces/ess/trial/events.ts

To start the test server:

cd x-pack/test/security_solution_api_integration

node ../../../scripts/functional_tests_server.js --config ./test_suites/investigation/timeline/security_and_spaces/configs/ess.basic.config.ts

Once it's started, open a new terminal and go to the same folder

node ../../../scripts/functional_test_runner --config=test_suites/investigation/timeline/security_and_spaces/configs/ess.basic.config.ts

@logeekal https://github.com/elastic/kibana/pull/188855 removes the duplicated serverless tests. Once it's merged, the path of timeline serverless tests will be the same as ESS tests.
