Adjust runtime feature validation logic

Removes compile-time checks in `sqlx-rt` that prevented
multiple runtime features (_rt-actix, _rt-async-std,
_rt-tokio) from being enabled simultaneously. The TLS
feature conflict check is also modified to error if
`_tls-rustls` is enabled, rather than when both TLS
backends are active.

CI changes:
- Expand `check` job matrix to include async-std and actix runtimes.
- Pin one `cargo check` invocation to `runtime-tokio-rustls`.
- Remove `--all-targets` from two `cargo check` invocations.

Fixes a typo in `sqlx-macros` (`procmacr2` -> `procmacro2`).
