Using semihosting with no debugger attached

Currently it's not possible to run code that contains semihosting calls without having a debugger attached, since semihosting relies on the debugger catching bkpt 0xab and without a debugger, this will trigger an exception and halt the mcu in most cases. I read that some semihosting C runtime provides an exception handler that is able to ignore this exception so that the mcu keeps running even without a debugger attached.
Even though semihosting is not meant to be used without a debugger, it might be useful to be able to run without one. It should at least be mentioned in the docs to make developers aware of it. Otherwise they might wonder why their code stops working when they plug out the debugger.
Unfortunately, this crate can't patch the vector table to catch and ignore the exception automatically, but we could try to find a way to make it trivial for the user to install such a handler (like providing the handler and the user just has to add it to the vector table)

Start by reviewing the crate's semihosting implementation and existing documentation; the issue does not name specific files or tests. Determine whether the scope is documentation only or also a user-installable exception handler, then document the no-debugger behavior and ensure any proposed handler can be added to the vector table as described.
