gdbstub: Introduce gdb_get_float64() to get 64-bit float registers

Browse source 
When converted to use GByteArray in commits 462474d760 and
a010bdbe71, the call to stfq_p() was removed. This call
serialize a float.
Since we now use a GByteArray, we can not use stfq_p() directly.
Introduce the gdb_get_float64() helper to load a float64 register.

Fixes: 462474d760 ("target/m68k: use gdb_get_reg helpers")
Fixes: a010bdbe71 ("extend GByteArray to read register helpers")
