feat(tvix/tracing): apply EnvFilter to all layers r/8272

Currently we apply the EnvFilter only to the stderr output writer.
This didn't affect any other layer, like the otlp layer, causing spans
from `h2`, `tokio_util` or other third party crate dependencies to be
always sent out via OTLP.

This changes that behaviour, applying EnvFilter to all exports, leading
to a lot less spans being exported.
