Alex Zinenko 2996a8d675 [mlir] avoid exposing mutable DialectRegistry from MLIRContext ... MLIRContext allows its users to access directly to the DialectRegistry it contains. While sometimes useful for registering additional dialects on an already existing context, this breaks the encapsulation by essentially giving raw accesses to a part of the context's internal state. Remove this mutable access and instead provide a method to append a given DialectRegistry to the one already contained in the context. Also provide a shortcut mechanism to construct a context from an already existing registry, which seems to be a common use case in the wild. Keep read-only access to the registry contained in the context in case it needs to be copied or used for constructing another context. With this change, DialectRegistry is no longer concerned with loading the dialects and deciding whether to invoke delayed interface registration. Loading is concentrated in the MLIRContext, and the functionality of the registry better reflects its name.
