Ensure multiple shaded version of the same netty artifact can be loaded as long as the shaded prefix is different (#8207)

Browse Source 
Motivation:

We should support to load multiple shaded versions of the same netty artifact as netty is often used in multiple dependencies.

This is related to https://github.com/netty/netty/issues/7272.

Modifications:

- Use -fvisibility=hidden when compiling and use JNIEXPORT for things we really want to have exported
- Ensure fields are declared as static so these are not exported
- Adjust testsuite-shading to use install_name_tool on MacOS to change the id of the lib. Otherwise the wrong may be used.

Result:

Be able to use multiple shaded versions of the same netty artifact.
