target/arm: make 'arm core_state' command compatible with Cortex-M

Browse Source 
Tcl command 'arm core_state' was exposed even on Cortex-M devices.
However it returned message "Unsupported Command" without error status
on such device.

Set the only possible arm->core_state ARM_STATE_THUMB in armv7m init.
Block setting core_state to arm on Cortex-M.
