KVM: arm64: Lift instrumentation restrictions on VHE

With VHE and nVHE executable code completely separated, remove build configthat disabled GCOV/KASAN/UBSAN/KCOV instrumentation for VHE as these nowexecute under the same memory mappings as the rest of the kernel.No violations are currently being reported by either KASAN or UBSAN.Signed-off-by: David Brazdil <dbrazdil@google.com>Signed-off-by: Marc Zyngier <maz@kernel.org>Link:https://lore.kernel.org/r/20200625131420.71444-16-dbrazdil@google.com
