Cache collision when multiple servers are using core_composable

Problem/Motivation

This is a sister issue of 🐛 Cache collision when multiple servers are using the same schema plugin Active .

When more than one GraphQL server is using the core_composable schema plugin, a cache collision occurs and the schema of one plugin will be exposed for all of the servers.

Proposed resolution

Port the fix of 🐛 Cache collision when multiple servers are using the same schema plugin Active to CoreComposableSchema.
