parse.y: Mark enum output ports always as IMPLICT_REG
...
Unless explicitly declared a wire an enum output port is of variable type
and should be marked as IMPLICT_REG.
Currently this is only done when the base type of the enum is `logic`. But
it should be done for all enums regardless of their base type.
Without this change for example the following snippet
```
typedef enum {
A,
B
} E;
module M (
input E ei,
output E eo
);
always_comb eo = ei;
endmodule
```
fails with the following error message
test_enum.sv:11: error: eo is not a valid l-value in M.
test_enum.sv:8: : eo is declared here as wire.

now the decorations make it to the code generators.
