[eduard13]

Description (*)

This PR fixes the caches that don't no instance configured, as it's an optional argument.

Fixed Issues (if relevant)

1. Cache type without "instance" causes exception when disabling the module through "Cache Management" in the backend #26224: Cache type without "instance" causes exception

Manual testing scenarios (*)

1. Create a cache type using "cache.xml" without the "instance" argument

<config .../>
    <type name="exceptional_cache_type">
        <label>Exceptional Cache Type</label>
        <description>An exceptional cache type using a quantum computer</description>
    </type>
</config>

2. Go to "System > Cache Management" in the backend
3. Check the checkbox of the cache type "Exceptional Cache Type"
4. Select "Disable" and click "Submit"

Here is some useful tips how you can test your changes using Magento test environment.

Hi @eduard13. Thank you for your collaboration. Please, join the discussion in the original issue. We have one more option here: throw an exception with the particular message instead of accepting a cache type with no implementation. But this point needs to be discussed additionally. I haven't found a use case for a cache type with no implementation

Hey @eduard13. I'm putting this PR on hold for now. We are going to discuss this topic internally. If you refer to the original issue, this case is not as straight forward as it seems to be.

Thank you.
