b22f94dc - [MLIR] Enable caching of type conversion in the presence of context-aware conversion (#158072)

[MLIR] Enable caching of type conversion in the presence of context-aware conversion (#158072) The current implementation is overly conservative and disable all possible caching as soon as a context-aware conversion is present. However the context-aware conversion only affects subsequent converters, we can cache the previous ones. This isn't NFC because if fixed a bug where we use to unconditionally cache when using the `convertType(Type t, ...` API, while now all APIs are aware of context-aware conversions.
