The arm64 version of the exception command was just defining the
undefined exception, but actually copied the AArch32 instruction.
Replace that with an encoding that is guaranteed to be and stay
undefined. Also add instructions to trigger unaligned access faults and
a breakpoint.
This brings ARM64 on par with ARM(32) for the exception command.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

The 'exception' command allows to test exception handling.
This implementation supports ARM, x86, RISC-V and the following exceptions:
* 'breakpoint' - prefetch abort exception (ARM 32bit only)
* 'unaligned' - data abort exception (ARM only)
* 'undefined' - undefined instruction exception
