toolchain: bump rust toolchain version
1. allow unexpected cfgs in lib.rs, in this case
"no_global_oom_handling" is cause warnings [1]
2. for large code models the compiler (rust linkers) now put code and
data in `.ltext`, `.ldata`, `.lbss`, `.lrodata` instead of the
same `.text` , `.data` ... etc. We are adjusting accordingly in the
linker script.
3. unsafe assertions identified undefined behaviours, in this case a repr(C)
struct was not mared as repr(packed), therefore having an unexpected
size. The unsafe assertions was not enabled by default in debug
builds so the idt setup code with from_raw_parts_mut() has been
working on UB. Glad we can catch this....
