Update trampoline to ~1.87 nightly

[samypr100]

Summary

1. Given the upcoming 1.89 update, this bumps uv-trampoline to "~1.87" (closest nightly) from "~1.86" (closest nightly).
2. Adds additional CI check for arm builds now that runners are available.

I wasn't sure the MSRV policy applies to uv-trampoline, so I didn't go for higher than ~1.87 nightly.
This PR also fixes a build issue starting after 1.87 where fma and fmaf symbols were missing.
Temporarily dded #[allow(clippy::ptr_eq)] to close_handles as this lint should not trigger anymore in 1.88 and above.

Test Plan

Existing tests and local build process. I did not commit the built binaries for security purposes.
