vlib,tests: fix array's param use signed int

[kbkpbot]

This PR fix vlib for future apply 64bit int.
Allow use i64, i32, i16, i8 as an array's param.

And also fix vlib/v/gen/c/testdata/translated/ files to workaround int in source code and generated code.

imho change the check to:

    if sym.kind !in [.int, .i32, .int_literal] {
        c.error('array ${para} needs to be an int', pos)
    }

sizeof(i32) is always <= sizeof(int) even when int becomes 64 bit, so passing an i32 value to that field should be allowed

Excellent work.
Thank you @kbkpbot 🙇🏻‍♂️.
