Fix ArrayWrapper inlining to go to pyx only, not pxd

Re-enable ArrayWrapper inlining with the fix that adds ArrayWrappers
to top_level_pyx_code instead of top_level_code. This ensures:

- ArrayWrappers are only placed in .pyx files (not .pxd files)
- No Cython declaration conflicts when projects have their own ArrayWrappers
- Projects can now remove their own ArrayWrapper definitions and use autowrap's

Benefits for projects using this:
- Additional integer array types (Int8-64, UInt8-64)
- Extra methods: __init__(size), resize(), size()
- Better documentation
