perf(hogql): Speed up hogql queries

[timgl]

Problem

(rerun of #27451 which created issues with the caching, so removed that for this PR)

create_hogql_database is slow (somewhere between 1-1.5 seconds per run for team 2), and we run it multiple times for a single query.

This should make every query we run 1-2 seconds faster.

Changes

make sure we only run create_hogql_database once

Does this work well for both Cloud and self-hosted?

PR Summary

Here's my review of the performance optimization changes for HogQL queries:

Optimizes HogQL query execution by preventing redundant database creation operations that were causing 1-1.5 second overhead per query.

Key changes:

• Moves create_hogql_database call into initial context creation in query.py rather than calling it multiple times
• Adds null check for context.database in printer.py to avoid recreating database if it already exists
• Maintains database creation within HogQLContext to ensure proper team_id validation
• Consolidates database initialization timing measurement under "create_hogql_database" block

The changes look well-structured and should provide significant performance gains by eliminating duplicate database creation overhead. The approach maintains proper security checks while improving efficiency.
