d3dcompiler_qt: Remove directory creation inside the proxy library

Use of mkpath/mkdir is removed in order to make the proxy less
invasive when there is no compiler service running. Creation of the
directory structure is fully the service's responsibility.
Service availability is now only checked once, at the first invocation of
D3DCompile, as it is expected to be started before the application.
