accel: Remove AccelOpsClass::supports_guest_debug

Browse Source 
Now accelerators hold the 'guest debug supported' information
in their state, accessible by the common code. No need to call
a per-accelerator handler, simply check for the SSTEP_ENABLE
in AccelGdbConfig::sstep_flags.

Remove all AccelOpsClass::supports_guest_debug implementations,
inline gdb_supports_guest_debug() and remove the now unnecessary
KVMState::have_guest_debug field.
