RFR: 8353217: Build libsleef on macos-aarch64 [v2]

[Vladimir Ivanov]

> Build and use SLEEF library as a backend implementation for Vector API trigonometric functions on macosx-aarch64 platform.
> 
> It improves raw throughput and eliminates GC overhead of non-intrinsified Vector API operation.
> 
> PR includes build changes and libsleef sources relocation from `src/jdk.incubator.vector/linux/native/` to `src/jdk.incubator.vector/share/native/`.
> 
> Once libsleef library is present, existing code in `stubGenerator_aarch64.cpp` successfully links at JVM startup. 
> 
> Testing: hs-tier1 - hs-tier4, microbenchmarks
