Suggestion: Move parameter into module in number_test

I'm working on validating a parser for Verilog-AMS, which is
basically vanilla verilog + extensions + some backports from
SystemVerilog. Because of this shared heritage, quite a number
of the tests in this repository are applicable and helpful.
The number_test tests are useful also, because they test
lexing of numberic literals. There are two tests (_3 and _4)
that test SystemVerilog extensions, but the remainder are
Vanilla verilog modulo the fact that `parameter` statements
can't appear at top level in vanilla Verilog. By moving
the parameter statements inside the model, the test would
be valid in both vanilla and System Verilog. I understand
that this is not a Verilog-AMS test suite, but I was hoping
you might be open to generalizing the test files where the
particular feature being tested itself is not a SystemVerilog
extension, such that we may share some of these testcases
between this repository and our Verilog-AMS test suite.
