Frank Barchard 2404f9730e [libyuv] Rewrite LoongArch LSX/LASX kernels in compact inline asm
Reduce loop unrolling across LoongArch LSX (128-bit) and LASX (256-bit)
compare, row, rotate, and scale kernels to match SSE2/SSSE3 and AVX2
(1-2 vectors per iteration), rewrite intrinsics/macro implementations
into GCC/Clang inline assembly, update all _Any wrapper masks and
IS_ALIGNED dispatch checks, and port all remaining LSX Convert (+19) and
Rotate (+2) kernels to LASX for full parity:

ISA              | Compare | Convert | Rotate  | Scale
-----------------|---------|---------|---------|--------
MIPS/Loong (Any) |    1    |    68   |    4    |   20
  LSX            |    1    |    68   |    4    |   20
  LASX           |    1    |    68   |    4    |    0

Removes 1,935 macro/helper lines from loongson_intrinsics.h (-99.3%) and
reduces total LoongArch compiled .text size by 9,799 bytes (-25.1%
overall, -37.4% row_lsx.cc, -52.3% scale_lsx.cc, -31.2% rotate_lsx.cc,
-4.9% row_lasx.cc while adding +25 LASX functions):

File               | Before   | After    | Change
-------------------|----------|----------|--------
scale_lsx.cc.o     | 6,055 B  | 2,888 B  | -52.3%
row_lsx.cc.o       | 17,252 B | 10,792 B | -37.4%
rotate_lsx.cc.o    | 1,488 B  | 1,024 B  | -31.2%
row_lasx.cc.o      | 13,740 B | 13,072 B |  -4.9%
rotate_lasx.cc.o   |   544 B  | 1,504 B  | +176.5%
TOTAL .text        | 39,079 B | 29,280 B | -25.1%
