Rollup merge of #130077 - madsmtm:watchos-arm-unwind, r=workingjubilee
Fix linking error when compiling for 32-bit watchOS

In https://github.com/rust-lang/rust/pull/124494 (or https://github.com/rust-lang/rust/pull/124748), I mistakenly conflated "not SjLj" to mean "ARM EHABI", which isn't true, 32-bit watchOS uses a third unwinding method called "DWARF CFI".

So this PR is effectively a revert of https://github.com/rust-lang/rust/pull/124494, with a few more comments explaining what's going on.

Fixes https://github.com/rust-lang/rust/issues/130071.
