Rust 1.92.0 adds new test that require unwind table support to be
enabled by default. Set `default-uwtable = true` in the generated
target spec to match upstream behavior.

ref:https://github.com/rust-lang/rust/commit/fe66eaa67acc47525db6f13cf97d54780d87b805

Also ignore the no_std simple-runs UI test on ARM targets. The test
fails with panic=abort due to a known unwind table issue on 32-bit ARM
