Reduce used crates for public libraries

[akorchyn]

Currently, we have pretty huge primitive and core libraries that pull too many crates for their need. This issue is created as part of the code review process for #11639 to track improvements.

Recently, I have been working to improve that situation in the following PRs: #11462, #11597, #11578, #11639 That said, this process is far from being completed. As part of the work I have found potential improvements that could be made:

• Extract business logic from near-primitives
• near-async uses near-o11y for logging only. This crate is potential overkill
• near-store can feature gate metrics by that make near-o11y optional
• feature-gate serde implementation
• iterate over all libraries removing dependency for near-async where it is used only for near-time
• nightly pulls all optional dependencies. The current nightly fmt script prevents using the '?' symbol in the feature list, so it's impossible to have something like that: The default syntax enables optional dependencies that make nightly pull extra and unused deps.

Please, feel free to extend this list, and let's track it in one place.

@akorchyn there is issue with building specific intermediate nearcore crates. When I build near-epoch-manager, cargo complains about missing imports, which is solved by additional features propagating (e.g. rand) as in #11732 (WIP). Could you look into impacted crates as well?
