feat!(cargo-codspeed): Allow filtering by benchmark name

[GuillaumeLagrange]

This PR removes the confusion there was before between benchmark names and benchmark targets

Now, benchmark target filtering is only done through --workspace, --package and --exclude cli flags for both cargo codspeed build and cargo codspeed run.

In addition, cargo codspeed run now properly forwards the bench_name positionnal argument to the benchmark target, in order to filter benchmarks ran. This is a breaking change, but it makes cargo-codspeed more in line with cargo bench

The second commit restores the option to filter benchmark target but now follows the cargo build API using the --bench target that can be repeated
