RFR: 8312425: [vectorapi] AArch64: Optimize vector math operations with SLEEF

[Hamlin Li]

Hi,
Can you help to review this patch?
Thanks

This is a continuation of work based on [1] by @XiaohongGong, most work was done in that pr. In this new pr, just rebased the code in [1], then added some minor changes (renaming of calling method, add libsleef as extra lib in CI cross-build on aarch64 in github workflow); I aslo tested the combination of following scenarios:
* at build time
  * with/without sleef
  * with/without sve support 
* at runtime
  * with/without sleef
  * with/without sve support 

[1] https://github.com/openjdk/jdk/pull/16234

## Regression Test
* test/jdk/jdk/incubator/vector/
* test/hotspot/jtreg/compiler/vectorapi/

## Performance Test
