CMake: Add stripping

- Strips binaries on gcc/clang
  - Affects Linux binary size: from 14.2mb to 6.1mb for static, and from 3.1mb to 2.6mb for shared
  - Does not affect wasm binary size
- Fix building static linux binaries on Ubuntu 22.10 by renaming a few functions in libcelt that clash with system libopus
- Fix building wasm binaries on systems with Vulkan installed
