Subject: [PATCH] fix(no_std): propagate `std` feature flag to dependencies
 (#1838)

Disables `std` feature flags in dependencies and only enables them with
`ratatui` and `ratatui-core`'s `std` feature flag. This partially fixes the
issue of still depending on `std`, when `std` feature flag is disabled.
