And enable LASX by default for LoongArch builds, because LASX is
widely supported among LoongArch desktops and servers, and performance
is better than with LSX alone.
Because the LoongArch SIMD code is written to only compile if the
respective codegen option is enabled, but the defaults and availability
differ between compiler versions and target `-march` setting, the
codegen flags are explicitly added to CFLAGS for wider compatibility.

Add a Neon implementation of the Convert8To16Row kernel. Compared to the
C implementation we can take advantage of knowing that the "scale"
parameter is always an unsigned power of two and fits in 16-bits,
allowing us to combine this with the shift and avoid needing to widen
the input data.

There are a few added source files since the (re-)addition of GYP build
support, for better SIMD optimization support (AArch64 SME & SVE,
LoongArch LSX & LASX, RISC-V RVV). This CL covers the LoongArch part in
preparation of fixing GYP builds for this architecture.
The files' arch-specific contents are all gated behind preprocessor
macro checks, so it is safe to have everything included in the build
unconditionally.

Several consumers of libyuv do unified sources build where many source
files are #include'd together to make compilation units larger and allow
for more optimization chances. But for LoongArch there is a wrinkle:
LASX and LSX code paths are implemented in separate files, unlike the
other currently supported architectures, and some definitions are
duplicated e.g. struct RgbConstants.
Since the duplicated content is identical across the two files, short of
some bigger refactoring, we can simply place #ifdef guards around the
definitions to fix unified sources build for LoongArch.

The existing code for creating RGB565 data in SVE2 and SME produces two
vectors of interleaved 16-bit elements due to the nature of how SVE
widening instructions operate. This means that the indices of the 16-bit
data created appear in the two result vectors as such:
z18.b: [elem0 byte0, elem0 byte1, elem2 byte0, elem2 byte1, ...]
z19.b: [elem1 byte0, elem1 byte1, elem3 byte0, elem3 byte1, ...]
This is problematic for the final (predicated) iteration of the
conversion since the p1 predicate input to the ST2H instruction controls
storing the four bytes corresponding to the first two elements, in the
first two bytes of z18 and z19. This means that in the case that the
width is an odd number there is no way of storing just elem0 in z18
individually.
This patch addresses this by permuting the z18/z19 data such that the
two bytes from each element are split evenly across the two vectors:
z20.b: [elem0 byte0, elem1 byte0, elem2 byte0, elem3 byte0, ...]
z21.b: [elem0 byte1, elem1 byte1, elem2 byte1, elem3 byte1, ...]
Since we would now always store the same lanes from both vectors we can
continue to use the same predicate without further changes.
The existing (non-tail) loop body utilizes an all-true predicate so we
can avoid the extra permutes in this case, avoiding any performance
degradation.
