Do not report detekt LargeClass issues on test classes (#7713)

detekt's default configuration excludes test source sets from
`TooManyFunctions` and `StringLiteralDuplication`, but not from
`LargeClass`, so large test classes were reported and had to carry a
`@Suppress("LargeClass")` annotation.

Add the same kind of exclusion to the `LargeClass` rule in
`tools/detekt/detekt.yml` and remove the 24 now-redundant suppressions
from test files. The two remaining suppressions are in production code,
where the rule still applies.
