"cargo test" jobs optimization (#6606)

* change (ci): 3 jobs in 1 decreases concurrency and is more effectiv; w/o release it's ~20% faster, but needs testing on prod; wasmtest tests are already running within cargo test --workspace

* fix (test): these ones were failing on nightly

* save: cargo profiles [skip ci]

* change (ci): one test to run them all

* change (ci): rebase

* Revert "change (ci): rebase"

This reverts commit 8a6b7ea0.

* fix (config): fix manifest

* change (ci): bench release
