Issue description

Following #61691, it seems Android editor builds are failing in master due to an error in the etcpak dependency with some NEON intrinsics:

thirdparty/etcpak/ProcessRGB.cpp:3259:16: error: argument value 4 is outside the valid range 
        return vdupq_lane_s16( vget_low_s16( multipliers ), ClampConstant( Lane, 0, 4 ) );

I've had to fix similar issues in the past (wolfpld/etcpak#25), seems like my fixes worked for NDK r21 but not for NDK r23 or some of our build config changes. CC @madmiraal

Googling a bit gives https://reviews.llvm.org/D74619 which sounds like a change in Clang to do better validation of input to these intrinsics. So this probably just needs clamping between 0 and 3 instead of 0 and 4 upstream, I'll test and PR.
