devel/wasi-libc: update to sdk-34

Changes: https://github.com/WebAssembly/wasi-sdk/releases/tag/wasi-sdk-34 https://github.com/WebAssembly/wasi-sdk/releases/tag/wasi-sdk-33 - sync CMAKE_ARGS from wasi-sdk - consolidate wasi-libc's plists, they have been identical after cmake transition - bump all existing WASI toolchain ports Consumer PORTREVISIONs to be bumped
