[feat] about Tauri support for RISC-V platform

[lily-Robot]

Describe the problem

I am evaluating the possibility of using Tauri to build desktop applications for the RISC-V platform. I would like to know if Tauri currently supports the RISC-V architecture, and whether there are any success stories or documentation available that could help me compile Tauri applications for RISC-V?

Describe the solution you'd like

If there is any relevant information or advice, could you please share it? Thank you!

Or rather, I'd like to know how to port it, which is currently on the RISCR V 64 platform, Porting packages such as node, gtk, chorme is approaching maturity. I would like to participate in RISC V 64 support if I can

I'm not aware of anything other than #8326 which is not much 🤷

I'm also interested in building Tauri apps for (and on) riscv architecture. So far I've tried the following inside a QEMU emulator. Using the riscv64-virt image and inspired by https://gist.github.com/apivovarov/98120ffb2d92f9dfce39925801271606.
But without success.

6.8.12-riscv64

Rust (https://doc.rust-lang.org/beta/book/ch01-02-hello-world.html) works fine on riscv:

Hi, I want to share some things I know.

According to the documentation, Tauri's webview (Linux) is built on top of WebKitGTK, I have submitted some RISC-V patches to WebKit over the past few months, so currently, compiling WebKit on the RISC-V platform should be ok, and some linux distributions have successfully packaged webkitgtk (appreciate their work), such as：WebKit/WebKit#36459 (comment)

However, jit is not fully supported, so there will be an impact on speed

👌 非常感谢，jit 应该问题不大
