Merge #263p-sh-v0.5.3c-m-sh-v0.3.5
263: Import cortex-m-semihosting and panic-semihosting into this repo r=adamgreig a=jonas-schievink
Motivation:
* Allows writing QEMU tests for `cortex-m`'s functionality that use semihosting to control QEMU. Previously these crates would pull in another cortex-m version, which doesn't work. Now they have a `path` dependency on the root crate.
* Lets us share the outline-inline-assembly setup and `cargo-xtask` in general.
* Lets us share CI and bot setup between more crates.
* 2 fewer repos to triage and keep track of (I'll transfer their issues after this is merged).
I also want to import cortex-m-rt, but I'll do that in a later PR.
CI was updated to build-test all crates with all or most feature combinations, like it did before.
