Update trampoline to ~1.87 nightly (#15052)

## 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.
