Long tezt: measure `tezt` start-up time
Context
Adds an LTF test that measures Tezt start-up time.
We've seen degradations of the start-up time recently, and this has a negative impact on developer performance.
Typically, we notice after the fact. LTF will help.
Manually testing the MR
$ docker-compose -f tezt/lib_performance_regression/local-sandbox/docker-compose.yml up -d
$ TEZT_CONFIG=tezt/lib_performance_regression/local-sandbox/tezt_config.json dune exec tezt/long_tests/main.exe -- --file tezt_load_time.ml -v
then go to http://localhost:3000 (or directly to http://localhost:3000/d/longtezts/long-tezts?orgId=1&viewPanel=39).
