Update astcenc to the upstream 5.3.0 release

Browse Source 
This is mostly a maintenance update that brings the compressor inline
with the recently published Khronos Data Format Specification 1.4
release which clarified some ambiguity in the specification. This update
also gives minor codec optimizations, bug fixes, and image quality
improvements.

The biggest improvement for Godot is that builds using MSVC cl.exe will
now correctly default to the SSE2-optimized backend rather than the
reference C backend. This makes compression more than 3 times faster.
Builds using other compilers (GCC, LLVM/Clang) were not impacted by the
underlying issue, and see no performance uplift.
