Convert the crash_debug option to Kconfig as CONFIG_CRASH_DEBUG. This
was previously togglable on the command line so this adds a message for
users enabling it from the command line to tell them to enable it from
make menuconfig.

This patch:
* enables the gdbstubs to properly access hypervisor memory;
* prevents an assertion failure in __spurious_page_fault's call
to map_domain_page if such accesses fail, by testing in_irq();
* prints some additional helpful messages;
* fixes the endianness of register transfers from the gdbstubs
so that gdb is much less confused.
* fixes the documentation in docs/misc/crashdb.txt
