target/loongarch: Split fcc register to fcc0-7 in gdbstub Since GDB 13.1(GDB commit ea3352172), GDB LoongArch changed to use fcc0-7 instead of fcc register. This commit partially reverts commit 2f149c759 (`target/loongarch: Update gdb_set_fpu() and gdb_get_fpu()`) to match the behavior of GDB. Note that it is a breaking change for GDB 13.0 or earlier, but it is also required for GDB 13.1 or later to work.
