APPBROWSER-298: Workaround Bifrost shader compiler issue

On Bifrost platform, we got this compile error for statement "data = unpack8_half(src_ptr[0])"
Error: Compiler log:
2:532: S0001: Function call discards 'readonly' access qualifier.

And we need to change it to "data = unpack8_half(uvec4(src_ptr[0]))"
