Enable resource reference feature by default (#5905)
* Enable resource reference feature by default

Unless the PULUMI_DISABLE_RESOURCE_REFERENCES flag
is explicitly set to a truthy value, the resource reference feature is now
enabled by default.

* Set AcceptResources in the language SDKs

This can be disabled by setting the `PULUMI_DISABLE_RESOURCE_REFERENCES` environment variable to a truthy value.

/**
* Common code for doing RTTI typechecks. RTTI is done by having a boolean property on an object
* with a special name (like "__resource" or "__asset"). This function checks that the object
* exists, has a **boolean** property with that name, and that that boolean property has the value
* of 'true'. Checking that property is 'boolean' helps ensure that this test works even on proxies
* that synthesize properties dynamically (like Output). Checking that the property has the 'true'
* value isn't strictly necessary, but works to make sure that the impls are following a common
* pattern.
