For header modify actions after decapsulation action, the header modify
actions should be applied to the inner layers.
Currently, it always treats the outermost layers as the corresponding
layer even though with decapsulation action.
Add the layer validation with decapsulation for the header modify action
and fix the incorrect layers chosen in header modify action with
decapsulation action.

Currently, the flow validate function only validate the outermost layer
with the header modify actions. If there is decapsulation action before
the header modify action, the validation should choose the inner layer
for validation.
Add decapsulation check when validate with the header modify actions.
Choose the inner layer once there is decapsulation action.

Currently, for header modify actions after tunnel decapsulation, the
header modify actions will still select the old outermost layer type.
It will cause header modify actions get the wrong layer type.
Add the tunnel decap flag to indicate the layer type to get for header
modify actions.
