xuxingliang e7c2e7c576 tools/gdb: use remote-register standard 
GDB uses remote-register to describe g/G packet. Whatever the target is,
we can always find out the register offset in packet by `maint print
remote-registers`.

In NuttX, we follow the same standard to prepare the packet, in both
coredump and GDB stub.

For example, the CPSR for arm-v7a is at register number of 25, byte
offset of 164. So we define the CPSR in g_reg_offs (164 /4 = 41)th
elementent.

If GDB stub supports qXfer feature, then GDB will ask stub for target
descriptor, which is a standard xml file. If this file is provided, then
the register order is also changed. It's also reflected in 'maint print
remote-registers' output. JLink GDB server supports it for example.

We always use manually added second inferiort to query the original
remote register layout. So it can match with tcbinfo.
