Open generic enumerable resolution fix #87017

[mesakomarevich]

• Fixed erroneous resolution of enumerables
• We now attempt to match each descriptor against both the service type and implementation type of cached call sites to account for slot mismatches, which can occur when a call site is cached, such that the slot order of the cached call sites does not match the expected order of descriptors
• Added unit tests to validate said functionality
