HybridCache: reflect API merge into runtime

In runtime 103103, the proposed HybridCache API was moved from a placeholder in aspnetcore into runtime (which owns the Microsoft.Extensions.Caching.Abstractions library). This means that the original API in aspnetcore is now duplicated and redundant. Additionally, runtime requested some minor last-minute API changes (mainly: prefer cancellationToken over token naming, and prefer IEnumerable<string> over IReadOnlyCollection<string> for tags parameter)

This PR reflects this merge - removing the duplicated APIs, and fixing the changes impacted by the API delta.

Since 103103 was merged immediately before the preview 7 snap, this will need applying both in main and release/9.0-preview7 after the runtime deps are updated (this is the release/9.0-preview7 version). Until runtime is built and the deps are updated, aspnetcore may be unbuildable.

Cross-reference: #56945 (main)

Hey @dotnet/aspnet-build, looks like this PR is something you want to take a look at.

Changes look good to me as far as reflecting the API that was ultimately approved into runtime.

Should cherry-pick this into #56962

[mgravell]

@wtgodbe lets see if this works... changed target/base from release/9.0-preview7 to darc-release/9.0-preview7-c259b2cd-b00e-4c3b-b2fb-6b98cf9f247a

tested locally - needed to add back a few more "unshipped" (I guess I got carried away with the del) - should build now

[mgravell]

@wtgodbe definitely improving - https://github.com/dotnet/aspnetcore/pull/56946/checks?check_run_id=27868375271 still has some unrelated (I hope!) errors in AesGcmAuthenticatedEncryptor

Something is up with "Linux Musl ARM" and "macOS arm64" like they haven't got the updated bits - taking a peek, but EOD here
