feat(tvix/store): support RUST_LOG env var r/7723

This allows selectively increasing the log level for only parts of the
stack.

For example, the following RUST_LOG env var enables "tracing" level
logging for `tvix_store` and `tvix_castore`, while keeping it at "info"
for the rest of the stack:

export RUST_LOG='info,tvix_store=trace,tvix_castore=trace'

It only affects logs, not traces (if enabled).
