[#579] [#581] Use 'core' and 'alloc' instead of 'std'

[elBoberido]

Notes for Reviewer

This PR adds the clippy::std_instead_of_core, clippy::std_instead_of_alloc and clippy::alloc_instead_of_core warnings to all crates that are not no_std. This will reduce the work when we tackle the challenge to make the crates no_std.

Where possible, all occurrences of std are replaced with core or alloc.
