pcb: power: Add `PWR_FLAG` symbolsHEADmain

This resolves ERC issues. The ERC complains that an power input is not
fed by a power output if there is a component like a ferrite bead or 0
Ohm resistor between the two.

The `PWR_FLAG` tells the ERC that it was explicitly checked that this is
not a mistake.
