why is this called embedding?

use default here to avoid it cluttering up the IR?

Elastic-miter needs to know the number of buffered tokens. This PR adds an attr
debugCounterto BufferOp to enable the export of token counter.This PR is needed by #391 and I totally forgot about it.
Since the counter is also useful for RTL debugging, I also added the counter to the VHDL beta backend.
