feat: allow building with the system Lua

[Kladki]

As per #943 (comment)

I tried to use default-features = false in the deps of yazi-fm and yazi-cli and have vendored-lua to be default in the dependencies, but when I did that it would just build with vendored lua every time. This is the only method that I could get to actually work, sorry if it's not ideal. :(

Is it possible to still keep each crate's default = [ "vendored-lua" ], but prevent them from being referenced in e.g. yazi-fm and yazi-cli using something like yazi-dds = { path = "../yazi-dds", version = "0.2.5", default-features = false }?

[Kladki]

I can try, but that would likely require setting default-features = false in every Cargo.toml as some of the other yazi dependencies depend on other ones which use the ones which depend on mlua.

[Kladki]

Done. Nvm forgot to add the defaults again No apparently they were already there, ready!

[sxyazi]

Why do we need to add default-features = false to yazi-core? yazi-core is not the entry point of the program, is this necessary?

[Kladki]

Yes, because that dependency would otherwise expect to have those features, and we cannot override that without making enabling that feature not the default.

[Kladki]

cargo tree seems unreliable for these tests, so I just eza -l target/release and compare the sizes. Without this there is no size difference between the default and --no-default-features, but with this there is a difference.

[sxyazi]

What command did you use for building?

[Kladki]

cargo build with and without --release and with and without --no-default-features
