Stabilize the strip profile option, now that rustc has stable `-C s…

…trip`

rust-lang/rust#90058 stabilized `-Z strip` as
`-C strip`. Stabilize the corresponding Cargo option.

Update the documentation to move it from the unstable reference to the
profiles documentation.

Update the tests to account for stabilization, but make them no-ops on
stable/beta for now until rustc 1.58 releases.

+#### strip
+
+The `strip` option controls the rustc `-C strip` option, which directs rustc to
+strip either symbols or debuginfo from a binary. This can be enabled like so:

+```toml

+Other possible string values of `strip` are `none`, `symbols`, and `off`. The

+You can also configure this option with the two absolute boolean values
+`true` and `false`. The former enables `strip` at its higher level, `symbols`,
