Direct invocation asset execution context

[jamiedemaria]

Summary & Motivation

This PR introduces a direct invocation AssetExecutionContext. The underlying op_execution_context is a DirectOpExecutionContext. Methods on AssetExecutionContext that have their own implementations, rather than passing through to a method on the op execution context, and access values not available during direct invocation will need to be re-implemented on the DirectAssetExecutionContext (but there are none of those in this PR). The bound/unbound state of this context is maintained on the underlying op context

Introduces a parent class for DirectOpExecutionContext and DirectAssetExecutionContext so we can do type checking in the direct invocation code path
