Possibly build this for ARM-based Ubuntu?

Today, fetch_qt6 always gets an x86_64 binary, even on Ubuntu Server. This makes this completely unusable there, and removing the fetch call still doesn't allow Bazel to find a system ARM-friendly qt6.

ARM support on Linux should be not to hard

look for thing like this:

qt_toolchain(
    name = "qt_linux",
    data = [
        "@qt_linux_x86_64//:moc",
        "@qt_linux_x86_64//:rcc",
        "@qt_linux_x86_64//:uic",
    ],
    moc_cmd = "$(location @qt_linux_x86_64//:moc)",
    rcc_cmd = "$(location @qt_linux_x86_64//:rcc)",
    uic_cmd = "$(location @qt_linux_x86_64//:uic)",
)

We need to add something like this:

qt_toolchain(
    name = "qt_linux",
    data = [
        "@qt_linux_arm64//:moc",
        "@qt_linux_arm64//:rcc",
        "@qt_linux_arm64//:uic",
    ],
    moc_cmd = "$(location @qt_linux_arm64//:moc)",
    rcc_cmd = "$(location @qt_linux_arm64//:rcc)",
    uic_cmd = "$(location @qt_linux_arm64//:uic)",
)

And we need a prebuild Qt version -> https://github.com/Vertexwahn/rules_qt6/blob/main/docs/prebuild_qt_versions.md

Can imagine that it works straightforward.

Not sure if I will time for this...
