Check the selected processor and target for compatability. about probe-run

This sounds like a good idea to me. I think we may only be able to implement this in a "best effort" manner though rather than as something with 100% accuracy.

Impl notes from the top of my head:

1. look into the core_type field of this probe_rs::Target

   probe-run/src/main.rs

   Line 127 in 5fe5ed4

   let target = probe_rs::config::registry::get_target_by_name(chip)?;

2. try to extract the compilation target (e.g. thumbv6m-none-eabi) from this path. Note that probe-run can be invoked like this: probe-run ./my-elf; in that case there's no target information in the path (the None case)

   probe-run/src/main.rs

   Line 122 in 5fe5ed4

   let elf_path = opts.elf.as_deref().unwrap();

3. compare (1) and (2) and emit a suggestion or not

   • for M0, target MUST be thumbv6m-none-eabi
   • for M3, target SHOULD be thumbv7m-none-eabi
   • for M4 and M7, target SHOULD be thumbv7em-none-eabi. (thumbv7em-none-eabihf may also be OK but probe-rs has no information about FPU support)
   • for Riscv, I don't think we can give any suggestion as we don't have any info about instruction set support from probe-rs (I vs IMAC vs IMC)

Which compilation should it be in case of CoreType::Armv8m which is Cortex M23 M33?
In the "Platform Support" (link) list I can find thumbv8m.base-none-eabi, thumbv8m.main-none-eabi and thumbv8m.main-none-eabihf. Can it be any of them?
