Summary:
This patch replaces the manual lock/unlock calls for gaining exclusive access to the disassembler with
a RAII-powered access scope. This should prevent that we somehow skip over these trailing Unlock calls
(e.g. with early returns).
We also have a second `GetDisasmToUse` method now that takes an already constructed access scope to
prevent deadlocks when we call this from other methods.
