Internals: clean up begin blocks and lifetimes in foreach loops (#5306) 
According to IEEE 1800-2023 12.7.3, the loop creates an implicit block
around it, containing declarations of the loop variables with automatic
lifetime.

No functional change intended.

Geza Lore d330100542 Create implicit nets for inputs of gate primitives. 
Prior to this we failed to create implicit nets for inputs of gate
primitives, which is required by the standard (IEEE 1800-2017 6.10).
Note: outputs were covered due to being modeled as the LHS of
assignments, which do create implicit nets.
