[data.search.searchSource]: Expose SearchSource on server

[ppisljar]

In order to support expressions on the server we need searchsource available there.

Blocks: #65067

Blocked by:

• make low-level search API the same on the client & server
• make agg configs and agg types available on the server
• make filters, query and timefilter interfaces & helpers available on the server

Prep for cutover:

• clean up utils
  • kibana_utils
    • expose fieldWildcardFilter on server
    • import KbnError & InvalidJSONProperty from common directory
  • kibana_legacy
    • expose migrageLegacyQuery on the server
  • SearchError: convert to type; appears to only be used as a type
• pass dependencies in through the service definition
  • cleanup injectedMetadata dependency
    • take in required configs directly & perform injectedMetadata lookup from search_service instead: esRequestTimeout, esShardTimeout, esApiVersion
  • cleanup uiSettings dependency
    • take in only the required settings, and provide everything via a getConfig function
• remove usage of legacy ES client [Search] Remove legacy ES client #55139

Cutover:

• move items to common:
  • move items from search/legacy to common:
    • fetchSoon
    • callClient
    • defaultSearchStrategy
    • getMSearchParams
    • types
  • move items from search/fetch to common:
    • types: FetchOptions, RequestFailure
    • utils: getSearchParamsFromRequest
    • handleResponse: provide as an optional callback to SearchSource
• export separate client/server contracts & update mocks

@elastic/kibana-reporting-services needs this enhancement to provide a better CSV export implementation.

Currently we must take all the all, or almost all, of the search query used in the browser and pass it through the CSV export generation API. To provide better integration, we need to simply pass the ID of the saved search through the generation API. This enhancement would allow us to achieve that simpler architecture.
