Alan Hayward 48574d91bf AArch64 SVE: Support changing vector lengths for ptrace 
When writing registers to the kernel, check if regcache VG has been changed. If
so then update the thread's vector length, then write back the registers.

When reading registers from the kernel, ensure regcache VG register is updated.
The regcache registers should already be of the correct length.

Remove all the checks that error if the vector length has changed.

gdb/ChangeLog:

	* aarch64-linux-nat.c (store_sveregs_to_thread): Set vector length.
	* nat/aarch64-sve-linux-ptrace.c (aarch64_sve_set_vq): New function.
	(aarch64_sve_regs_copy_to_reg_buf): Remove VG checks.
	(aarch64_sve_regs_copy_from_reg_buf): Likewise.
	* nat/aarch64-sve-linux-ptrace.h (aarch64_sve_set_vq): New declaration.
