Add Linux Loongarch64 support

[beyond-1234]

Hi, since Go has added support for Loongarch64 since 1.18, so maybe we could have native build for Linux Loongarch64.

You can find a brief introduction about Loongarch here if it's not familiar to you.

notes:

• Linux identifies Loongarch64 as loongarch64 while nodejs treat it as loong64.
• Compiling the executable for loongarch64 requires the latest version golang.org/x/sys package. Details in the commit
