implement performance budgets for query results size

[pieh]

Warn whenever query result is large enough to cause frontend runtime perf implications. "large enough" is yet to be determined - any ideas?

Notes and questions:

• We only run queries that we need to, so getting size of queries that don't need to re-run will eighter need extra I/O or we will need to cache size of queries We started to keep track of page-data size in feat(gatsby): bundle and page-data stats for telemetry #20146
• What should be default budget for query result size?
• How dev can customize default budget? (maybe we don't want that?)

Related Issues:

• gatsby/cache-dir/loader.js eval's JSON on main thread, doesn't use fetch()
