xtensa: don't send window registers to GDB

Browse Source 
GDB considers window registers as pseudo registers, meaning that they
are calculated by GDB using the values of AR registers and windowbase.
This patch removes the window registers from the total number of
registers that QEMU will send to GDB, making the number of registers
match the one that GDB expects to see.
