Rollup merge of #147596 - thejpster:build-new-arm-tier2-targets, r=Mark-Simulacrum

Adjust the Arm targets in CI to reflect latest changes

* Adds build of `armv7a-none-eabihf` (#146522)
* Adds build of `armv8r-none-eabihf` (#146520)
* Drops build of `armeb*-none-*` (#146523)

I wasn't sure why `armv7a-none-eabihf` was missing from the build-manifest program, but `armv8r-none-eabihf` was there, as they were both Tier 3 targets up until very recently. So, I added it, but that might be wrong.
