chore(ci): collect sidecar logs for test jobs (#3864)

Lift sidecar log collection (`_DD_DEBUG_SIDECAR_LOG_LEVEL=trace` and
`_DD_DEBUG_SIDECAR_LOG_METHOD=file://${CI_PROJECT_DIR}/artifacts/sidecar.log`)
from `.asan_test` and `PHP Language Tests` up into `.base_test` so it
also applies to `.debug_test` (test_extension_ci, Unit, API unit,
Disabled test_c, Internal api randomized, Opcache, xDebug) and
`.cli_integration_test` (web/integration). The existing
`artifacts: paths: ["artifacts/"]` with `when: "always"` already uploads
the log on every run.
