WANG Rui 0d3a632202 LoongArch: Use rustc option -Zdirect-access-external-data
-Zdirect-access-external-data is a new Rust compiler option added in
Rust 1.78, which we use to optimize the access of external data in the
Linux kernel's Rust code. This patch modifies the Rust code in vmlinux
to directly access externa data, using PC-REL instead of GOT. However,
Rust code whithin modules is constrained by the PC-REL addressing range
and is explicitly set to use an indirect method.
