cmd/compile: remove {Mark,Pop}dcl calls in bimport

Browse Source 
These were previously only relevant for recording scoping level so
that invalid 'fallthrough' statements could be rejected. However,
that's handled differently since CL 61130 (in particular, there's no
use of types.Block anymore), so these calls can be safely removed.

Passes toolstash-check.
