Linking dynamic pipeline shader libraries on Linux doesn't work as-is

[expenses]

I had to make the below changes to rps_rpsl_host_dll.c to get dynamic libraries to work on Linux. Not sure how portable these changes are back to windows but I'm sure it's possible to work out something more platform-independent.

• Branch: https://github.com/GPUOpen-LibrariesAndSDKs/RenderPipelineShaders/compare/main...expenses:RenderPipelineShaders:linux-dynamic-libraries
• Shader compilation script: https://github.com/expenses/rust-rps/blob/1306c542a55c1c699374e7ee6c4bb09574380c98/compile_dynamic.sh
