Hexagon (target/hexagon) Only use branch_taken when packet has multi cof

When a packet has more than one change-of-flow instruction, only the first
one to branch is considered. We use the branch_taken variable to keep
track of this.

However, when there is a single cof instruction, we don't need the same
amount of bookkeeping.

We add the pkt_has_multi_cof member to the Packet structure, and pass this
information to the needed functions.

When there is a generated helper function with cof, the generator will
pass this pkt_has_multi_cof as a runtime value.

Hexagon (target/hexagon) Remove next_PC from runtime state

The imported files don't properly mark all CONDEXEC instructions, so
we add some logic to hex_common.py to add the attribute.
