[Security Solution] Upgrade Apollo dependencies

[rylnd]

We need to update our Apollo/GraphQL code to support #71393.

Broad goals:

• Upgrade (or remove) GraphiQL (see Upgrade documentation)
• Update our use of runHttpQuery

Current status: I have a spike branch here that begins this work. I've removed GraphiQL for now but we can add it back if needed.

I started fixing typescript errors related to our use of runHttpQuery but realized there are runtime errors preventing kibana from starting, so I'm currently looking into those.

Here is my old PR that maybe you will find helpful https://github.com/elastic/kibana/pull/58974/files#diff-84dba1d472f9e06c0896acd55b201204

Quick update: it seems like the team consensus is that the effort required here would be better invested in removing GraphQL entirely. I believe @XavierM will be working on this in 7.10; when we have a public issue I'll link that and close this.

[XavierM]

The goal is to try to remove our graphql in 7.10, but we can not promise to get all out it for 7.10. Let's see.

[rylnd]

Moving this to (at least) 7.11. We've moved much of our querying to use search strategies and remove our dependence on apollo, but we have a few outstanding graphql queries that depend on retrieval of saved objects, which existing search strategies do not support. I was unable to find an issue for said SO support; @XavierM, please link that issue here if/when it's created, and please correct any inaccuracies above.

[rylnd]

Update: a saved objects client is now available within search strategy handlers as of #80775. This should unblock the migration of timeline endpoints.

We replaced most of our graphQL endpoints in previous release, some with http endpoints and some with search strategy. I'm working on this in 7.13, and these are the graphQL we still have:

1. Notes - x-pack/plugins/security_solution/server/graphql/note/resolvers.ts
2. Timelines - x-pack/plugins/security_solution/server/graphql/timeline/resolvers.ts
3. PinnedEvents - x-pack/plugins/security_solution/server/graphql/pinned_event/resolvers.ts
4. Hosts - x-pack/plugins/security_solution/server/graphql/hosts/resolvers.ts

#95036

GraphQL is removed in 7.13.

We completely removed the apollo-server-core package in the PR linked above, so this issue can be closed 🎉
