freedreno/rddecompiler: Emit explicit scope for CP_COND_REG_EXEC

Due to the larger amount of conditional execution in newer traces
the flat view makes it hard to parse what might be conditionally
executed and what might now. This makes it easier to view by adding
a scope for conditionally executed commands which is indented to the
next level.
