They are not needed, and due to them there was a call to _xgetbv()
without a declaration of the function. This used to work because we
implicitly included intrin.h in all translation units with clang-cl, but
we want to stop doing that.

An SSSE3 version already exists, and an AVX2 version is available for
Visual C. This ports the function to AVX2 completing the AVX2 ports of
all YUV to RGB functions for AVX2 on gcc.

NV12ToRGB565Row for Intel is implemented as a 2 step conversion:
NV12ToARGBRow_SSSE3 and ARGBToRGB565Row_SSE2
NV12ToARGBRow has an AVX2 version, so this CL implements
NV12ToRGB565Row_AVX2 with call to NV12ToARGBRow_AVX2 and
ARGBToRGB565Row_SSE2.

When attempting to normalize function names to end in Row_SIMD it was made
harder with MIPS_DSPR2 naming convention.
Other CPUs do not include the vendor. This should be named consistently.
Removed the DISABLE_MIPS in favour of DISABLE_ASM for consistency with other
processors.

internal math of the fastrand function uses a multiply
and add that overflows a signed int. This triggers a
ubsan failure:
../../unit_test/../unit_test/unit_test.h:60:33: runtime error: signed integer overflow: 56248274 * 214013 cannot be represented in type 'int'
This change casts the intermediate math to unsigned
int to avoid the overflow.

The source is uint8 and the multiply is by 0x01010101 to replicate the byte to 4 bytes.
Changing the constant to 0x01010101u should avoid overflow.

odd height, the TestI420 unittest would not fill
the complete source buffer. This change handles
the odd height test case.

I420ToNV21 passes the wrong dst_stride_y when it calls I420ToNV12; parameter 8 (convert_from.cc:448) is src_stride_y but should be dst_stride_y. This causes image corruption when converting I420 -> NV21 with mismatched luminance strides.
