Provide optimized version in addition to the default "baseline" binary

[deanrih]

As far as I understand the currently proivided binary, at least on Linux, is more of a "baseline" version (taking example/parallel from something like Bun) which meant to be more compatible with more machine that do not have specific instruction.

However the drawback is that for something like Bun installation detection, as shown here

https://github.com/jdx/mise/blob/main/src/plugins/core/bun.rs#L189-L214

Lines 189 to 214 in 58a4276

	fn get_bun_arch_with_variants() -> &'static str {
	if cfg!(target_arch = "x86_64") {
	if cfg!(target_env = "musl") {
	if cfg!(target_feature = "avx2") {
	"x64-musl"
	} else {
	"x64-musl-baseline"
	}
	} else if cfg!(target_feature = "avx2") {
	"x64"
	} else {
	"x64-baseline"
	}
	} else if cfg!(target_arch = "aarch64") {
	if cfg!(target_env = "musl") {
	"aarch64-musl"
	} else if cfg!(windows) {
	"x64"
	} else {
	"aarch64"
	}
	} else {
	&ARCH
	}
	}
	}

means that, to my understanding, specifically on the "avx2" check won't ever to be true since it's not detected at build time

causing the non "baseline" result in the lines below to never resolved

	fn get_bun_arch_for_target(target: &PlatformTarget) -> String {
	let base_arch = Self::map_arch_to_bun(target.arch_name());
	// Handle qualifiers like musl, baseline, etc.
	if let Some(qualifier) = target.qualifier() {
	match qualifier {
	"musl" => format!("{}-musl", base_arch),
	"musl-baseline" => format!("{}-musl-baseline", base_arch),
	"baseline" => format!("{}-baseline", base_arch),
	other => format!("{}-{}", base_arch, other),
	}
	} else {
	base_arch.to_string()
	}
	}

resulting in Bun installation to always download the -baseline version instead the more optimized version, it is also confirmed when building from scratch as it doesn't "see" the "avx2" feature, I have to do something like line below to detect the "avx2"

RUSTFLAGS="--codegen target-cpu=native" cargo build --profile serious # or release

potentially can be solved by this too if you decide to install through cargo

RUSTFLAGS="--codegen target-cpu=native" cargo install mise --profile serious

however it would be nice if mise provide an optimized version, in this case one with avx2 support, alongside the "baseline" and have the installation shell script to have detection like what Bun do from the link below on line 105
