Subject: Migrate examples (#4920)

* Migrate cpu-hello-world to new slang API

    Migrate cpu-hello-world to new slang API, and also convert this example
    as one of the unit test.

* Add 'shader-object' to slang-unit-test

* Convert ray-tracing example into unit-test

    Convert ray-tracing example into unit-test

* Fix some replay bugs:
  - Wrong decode type in 'getEntryPointHostCallable'.
  - Mistakes in computing the output buffer size.
  - Wrong decode type in array size in specialize() call.
  - When capture entrypoint, we should increase the reference count
     for the allocated entrypoint recorder object, because that is
     allocated by record layer, it should be owned by the layer, user
     should not be able to free it.
  - Improve json consumer on the prelude text.

* Test verify change:
In our test, we add a "callIdx" string at beginning of the hash-code
string, as there could be more than one modules in the example, so they
could call 'getEntryPointHash' multiple times, in order for the test
can identify them, add "callIdx: <number>" as the key word.
