Make sure MSVC++ redistributable DLLs become part of the release

Make OSS libhermes ABI compatible with RN

Summary:
We removed a method that RN currently uses, which means that Hermes 0.2.x can not be used with RN <=0.60.5. See facebook#109

This diff adds a dummy passthrough method for linking compatibility.

Clean up unused createStoreOwnPropertyInst

Summary:
We have 4 diferent versions of createStoreOwnPropertyInst, defined in different places in IRBuilder.h.
Only 2 are used and one of them only has one occurance. Those definitions seem unnecessary to me and only increase the complexity of the API.
Clean them up

Remove const_cast in createSnapshotFromFile wrapper.

Summary:
The function is not annotated with `const` so `plain()` will return a non-const
reference to the undecorated Runtime already.  Seems like the const_cast was a
hold-over from a previous iteration.

Use correct name for stdin in source map

Summary: When running the Hermes compiler driver with `-output-source-map` `-emit-binary` and read input from stdin rather than a file, we currently hit an assertion failure because we initialise the list of sources to `{"-"}` but add mappings that refrence `"<stdin>"`. This diff fixes that.

remove memory allocation in signal handler

Summary:
Context: `ModuleIdManager` is introduced in SamplingProfiler to hold RuntimeModule alive with reference counting. With the new domain design, it is not necessary, holding strong references to Domain is enough. However, pushing a Domain into vector may cause memory allocation in signal handler causing potential deadlock/crash.
To solve this, two new methods `increaseDomainCount/decreaseDomainCount` are added to perform `domains_` storage management outside of signal handler.

To summarize, this diff does:
* Remove `ModuleIdManager` and directly use RuntimeModule pointers in stack frame.
* Introduce `increaseDomainCount/decreaseDomainCount` to manage `domains_` storage to avoid memory allocation in signal handler.
* Added a new testcase
