[jnimarshalmethod-gen] Fix registration on Windows

[radekdoulik]

Set parameters to registration method builder, to get rid of exception
we are getting on Windows. Looks like the S.L.E code still differs
between Windows and Mac.

Also report adding registration methods in verbose mode, similar as we
do with marshal methods.

The ArgumentOutOfRangeException mentined above:

error JM4006: jnimarshalmethod-gen: Unable to process assembly '.\bin\TestDebug\Java.Interop.Export-Tests.dll'
Specified argument was out of the range of valid values.
Parameter name: The specified parameter index is not in range.
System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
