refactor(tvix/castore): introduce "cloud" feature flag r/7749
This controls whether tvix-castore has support for various cloud
backends or not.

Use this to control the set of feature flags for the object_store
backend, and only enable the aws, azure and gcp ones if it's set.
In the future this can be used to enable/disable other cloud backends
too.

Without feature flags, `object_store` already supports the `InMemory`
and `LocalFilesystem` backends, and we also want to unconditionally
enable the `http` one. Make sure at least the construction of these
services is covered in the tests.

Similarly, the tvix-store crate, which provides the tvix-store CLI has a
`cloud` feature flag too (defaulting to enabled).
