linux-user/elfload.c: Add missing arm and arm64 hwcap values

Our lists of Arm 32 and 64 bit hwcap values have lagged behind
the Linux kernel. Update them to include all the bits defined
as of upstream Linux git commit a48fa7efaf1161c1 (in the middle
of the kernel 6.6 dev cycle).

For 64-bit, we don't yet implement any of the features reported via
these hwcap bits.  For 32-bit we do in fact already implement them
all; we'll add the code to set them in a subsequent commit.
