fhdl/verilog: avoid reg initialization in printheader when reset is not an int.
...
We should be able to reset a signal with the value of another one. Without this change it's not possible to do so since synthesis tools do not support initializing a signal from another one.

fhdl/decorators: make the transform logic more idiomatic
...
* the transformers work on classes and instances.
you can now do just do:
@ResetInserter()
@ClockDomainRenamer({"sys": "new"})
class Foo(Module):
pass
or:
a = ResetInserter()(FooModule())
* the old usage semantics still work
* the old DecorateModule is deprecated,
ModuleDecorator has been refactored into ModuleTransformer
(because it not only decorates things)

fhdl/verilog: add simulation parameter to avoid simulation tricks in synthetizable code

it's generally better to have identical code between simulations and synthesis, but here tricks inserted for simulation are clearly expected to be simplified by synthesis tools, so it's better not inserting them.
