add loongarch64 platform support

[wxpppp]

When I used the auditwheel tool to repair a wheel package on the LoongArch64 Alpine platform, I encountered an error. So, I added some LoongArch64 platform-related code to support musllinux and manylinux.

PS: Alpine v3.21 has support loongarch64 platform.(https://wiki.alpinelinux.org/wiki/Loongarch64)

Hello, can the code be adapted for manylinux_2_34?
It is recommended to support it from manylinux_2_31 like the riscv64 architecture.

GLIBC_2.34

• openEuler-22.03-LTS

GLIBC_2.36

• AnolisOS-23.1

GLIBC_2.38

• OpenCloudOS-23

Seems almost correct but I can't really check this.

You can run a LoongArch container environment on an x86 machine as follows:

docker run --rm --privileged ghcr.io/loong64/qemu-user-static --reset -p yes
# Debian
docker run --rm --platform linux/loong64 -it ghcr.io/loong64/debian:trixie-slim bash
