Semantic attributes for language runtime

[anuraaga]

Looked around and couldn't find these, does it make sense to have semantic attributes for a language runtime? For example

process.runtime.name - a name of a runtime, for example Oracle JDK, .Net Core, PyPy
process.runtime.version version of the runtime in runtime.name

For compiled languages I guess we wouldn't fill them, though putting information about the compiler (if available) could be an option.

I think it would make sense to add this 👍
For the runtime name I suggest adding a list of well-known values like we have for the database vendor (db.system) in the semantic conventions for DB calls.
