Parse the source for an ES module

CHAKRA_APIJsParseModuleSource(    _In_ JsModuleRecord requestModule,    _In_ JsSourceContext sourceContext,    _In_ BYTE* script,    _In_ unsigned int scriptLength,    _In_ JsParseModuleSourceFlags sourceFlag,    _Outptr_result_maybenull_ JsValueRef* exceptionValueRef);

• requestModule: The ModuleRecord being parsed.
• sourceContext: A cookie identifying the script that can be used by debuggable script contexts.
• script: The source script to be parsed, but not executed in this code.
• scriptLength: The length of sourceText in bytes. As the input might contain a embedded null.
• sourceFlag: The type of the source code passed in. It could be utf16 or utf8 at this time.
• exceptionValueRef: The error object if there is a ParseError.

The codeJsNoError if the operation succeeded, a failure code otherwise.

This API is experimental and may have breaking change later.This is basically ParseModule operation in ES6 spec. It is slightly different in that:a) The ModuleRecord was initialized earlier, and passed in as an argument.b) This includes a check to see if the module being Parsed is the last module in the dependency tree. If it is it automatically triggers Module Instantiation.
