arch/arm: Fix THREAD_MONITOR entry struct
On ARM, the __thread_entry struct pointer used when
CONFIG_THREAD_MONITOR is enabled was pointing to the initial exception
stack frame. That's not right: even though this contains all the same
info, it's not layout-compatible with the API struct. And once the
thread starts running, the ESF gets unwound and the memory recliamed
for the stack frame of the entry function!
Stuff the __thread_entry struct into its own memory at the bottom of
the stack like the other architectures do. Fixes #7541
