[usearch] add features

[toge]

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version.
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

usearch provides several options for external dependencies.

Would you give me more information?
I don't know how to improve it because I successed to find usearch package in my local environment.

If usearch can be used without the fp16 feature enabled then it should be removed from the default-features list

[JavierMatosD]

Is usearch useful without the fp16 feature enabled?
