feat: add getRemoteSize() to ImageService to enable customization of inferRemoteSize behavior

[rururux]

Changes

As discussed in the issue #14515 and #15067, the current implementation of inferRemoteSize had the problem of increased network traffic because it did not cache data.
To address this issue, I added a getRemoteSize property to the Image Service and implemented the publicly exposed inferRemoteSize API to utilize this property.
Additionally, for baseService's getRemoteSize, I configured a function that simply wraps the existing inferRemoteSize. This ensures no breaking changes occur for users who do not wish to see their behavior altered.

• Set getRemoteSize as an API of the Image Service.
• Modified the publicly exposed inferRemoteSize function to utilize the Image Service's getRemoteSize.
• Assigned the existing inferRemoteSize function to baseService's getRemoteSize. This prevents breaking changes and facilitates easy, lightweight extensions based on the existing implementation.

Testing

I implemented tests to verify that arbitrary processing can be configured and that delegation from baseService to the original inferRemoteSize is possible.

Docs

Since we are setting the existing inferRemoteSize as the default value, I don't believe this constitutes a breaking change. However, since we will be introducing a new property called getRemoteSize in the Image Service, I think the documentation will need to be updated.

As this is a PR introducing a new property, I would like to hear the opinions of the maintainers regarding this approach. Therefore, I will submit this PR as a draft for now.
