The existing tests reuse the intermediate buffers between the reference
and optimized implementations. In particular the existing tests appear
to pass even if the optimized implementation is completely empty, so
long as it does not modify the desintation buffers since these are
already filled with correct values from the reference code.
To avoid this, allocate separate buffers for optimized and reference
implementations to store intermediate data between function calls.
Additionally remove unused buffers from HalfMergeUVPlane_Opt tests.

This re-lands commit ba0bba5b2b7e38c9365a5d152b4efa0458863213.
Now with additional #ifdef __linux__ guards to avoid compiling
Linux-specific code on non-Linux platforms. Non-linux feature detection
will be added in a separate patch.
Using getauxval(AT_HWCAP{,2}) has the advantage of also working under
emulation where faking /proc/cpuinfo is not supported.
For the Chromium sandbox, getauxval is supported since API version 18.
The minimum supported API version at time of writing is 21 so we should
be able to use getauxval unconditionally. On the off-chance the call
fails it will return 0 and we will correctly fall-back to using only
Neon.
If we want to read the current CPU implementer or part number we could
do this by checking HWCAP_CPUID and then reading MIDR_EL1. This will
cause a kernel trap to emulate the EL1 read but should still be a lot
faster than reading the whole of /proc/cpuinfo.

In particular there are a few extensions that are interesting for us:
* FEAT_DotProd adds 4-way dot-product instructions which are useful in
e.g. ARGBToY.
* FEAT_I8MM adds additional mixed-sign dot-product instructions which
could be useful in e.g. ARGBToUV.
* FEAT_SVE and FEAT_SVE2 add support for the Scalable Vector Extension,
which adds an array of new instructions including new widening loads
and narrowing stores for dealing with mixed-width integer arithmetic
efficiently and predication for avoiding the need for "any" cleanup
loops.
This commit simply adds support for detecting the presence of these
features by extending the existing /proc/cpuinfo parsing, splitting it
into separate Arm and AArch64 functions for simplicity.
Since we have no space left in the bitset entries between Arm and X86
entries, we reuse some of the X86 entries for new AArch64 extensions.
This doesn't seem obviously problematic as long as we avoid setting
kCpuHasX86.

This function reads 2 byte values and writes the 2nd byte to the destination.
It turns out this is useful for P010ToNV12 as well, so adding the planar function allows a high level to call this.
And adds UYVY support for something YUY2 already had. Which is writing the 1st byte.

When doing 90 or 270 degrees rotation we need to do a rotate&scale of the UV planes, as there are no helper optimized functions to do this, we use the Y plane as temporal memory and perform each of the transforms independently:
First U plane is rotated, putting the result in the Y plane. After the rotation, the output has double the samples horizontally and half the samples vertically, so it is scaled into the final U plane. Same process is done with the V plane.
Last the Y plane that can be just rotated without scaling.
It would be great to have an optimized version for this, but maybe this is helpfull for triggering the discussions.
