[Logs + Metrics UI] Migrate to TS project references

[weltenwort]

Summary

Now that the Kibana build system supports using TypeScript project references (#46773), the infra plugin must be migrated to participate. This is part of the overall effort tracked at #80508.

Blockers

This is currently blocked by the migration status of some of the plugin dependencies:

• features
• usageCollection
• spaces
• data
• dataEnhanced
• visTypeTimeseries
• alerts
• triggersActionsUi
• ml
• observability
• licenseManagement
• kibanaUtils
• kibanaReact
• apm
• home

Acceptance criteria

The infra plugin can be referred to using a project refrence, which means it...

• has a tsconfig.json file which conforms to the documented form
• references the dependencies
• emits type definitions for its public API
• compiles in tsc's build mode

ℹ️ The ml (#90021) and observability (#89320) plugins are the only remaining unmigrated dependencies. They are about to be migrated which should unblock this issue.

The majority of the work can be done without waiting for other plugins to complete. Fleet used the approach suggested in #80508 (comment) for #87574 and it worked quite well

#90049 on APM takes a similar approach. If nobody has a draft up I can try to take a crack at it tomorrow.

#90118 is open as a draft. Will update once #87574 is merged.

#90118 is open as a draft. Will update once #87574 is merged.

That's great news! infra was the last thing #87574 was waiting for

kibana/x-pack/plugins/fleet/tsconfig.json

Line 36 in 5c955ff

// TODO { "path": "../infra/tsconfig.json" },

I'm watching #90118 and will merge #87574 as soon as that lands. Thanks, again!
