mozjs: add recipe for mozjs-128

mozjs-128 is the current esr release based on firefox 128

Add a new recipe and keep mozjs-115 as its still supported and used by polkit

- Remove two backported patches
- Remove a (hopefully) unneeded patches for musl (build for qemuarm/musl succeeded)
- Add dependency for cbindgen-native

+Subject: [PATCH] Rewrite cargo-host-linker in python3
+
+Mozjs compile failed with this failure:
+/bin/sh: /lib64/libc.so.6: version `GLIBC_2.33' not found (required by /build/tmp-glibc/work/corei7-64-wrs-linux/mozjs/91.1.0-r0/recipe-sysroot-native/usr/lib/libtinfo.so.5)
+
+Root Cause:
+cargo-host-linker has /bin/sh as it's interpreter, but cargo run the cmd
+with LD_LIBRARY_PATH set to recipe-sysroot-native. The host /bin/sh links
+libtinfo.so.5 under recipe-sysroot-native, which needs higher libc. But
+host libc is older libc. So the incompatible problem occurred.
+
+Solution:
+rewrite cargo-host-linker in python3
