Add capture logic to other interfaces. (#4412)

* Add capture logic to other interfaces.

Add capture logics to ISession, IModule, ITypeConformance, IEntryPoint
ICompositeComponentType.

Add few encode methods to encode the array.

Fix some capture logic in global session. We will not need to encode
the null_ptr output before actual actual of the captured APIs.
Previously we used this as a place holder, but it's actually not
necessary, it can be detected if the output is not captured during
replay.

* capture/replay: dump the shader files to disk

Dump the shader files to disk.
Also set a default directory for the capture files.
