Remove omsdk dependency from Dell OpenManage Ansible collection (ECS02C-251)

- Remove omsdk and omdrivers from requirements files (requirements.txt,
  test-requirements.txt, tests/unit/requirements.txt)
- Remove omsdk requirement lines from DOCUMENTATION strings in all 15
  affected plugin modules and 15 RST doc files
- Remove omsdk install instructions from README.md, tests/README.md,
  and EXECUTION_ENVIRONMENT.md
- Remove dead omsdk/omdrivers try/except import blocks from 10 modules
- Replace dead legacy function bodies (that used omsdk config_mgr,
  update_mgr, file_share_manager, etc.) with NotImplementedError in:
  dellemc_configure_idrac_eventing, dellemc_configure_idrac_services,
  dellemc_idrac_lc_attributes, dellemc_idrac_storage_volume,
  dellemc_system_lockdown_mode, idrac_firmware, idrac_lifecycle_controller_logs,
  idrac_network, idrac_syslog, idrac_timezone_ntp
- Rename is_omsdk_required -> is_legacy_idrac across plugins, tests,
  and integration test YAML files
- Rename update_firmware_omsdk -> update_firmware_legacy and
  update_firmware_url_omsdk -> update_firmware_url_legacy in idrac_firmware
- Rename omsdk_mock -> idrac_mock_obj in unit test fixtures
- Update YAML task names referencing omsdk to use 'legacy iDRAC' terminology
- Update ansible_doc.txt files to remove omsdk references
- Add targeted pytest.mark.skipif(not HAS_OMSDK) markers to 83 unit
  tests that test legacy omsdk code paths, allowing non-omsdk tests
  to run (243 pass, 83 skip)
