Add XNNPack build on Linux ARM64 and improve Linux CPU (#22773)

### Description
1. Add XNNPack build on Linux ARM64
2. Build only one python wheel for PR request.

[AB#49763](https://aiinfra.visualstudio.com/6a833879-cd9b-44a4-a9de-adc2d818f13c/_workitems/edit/49763)



### Motivation and Context
Why I add xnnpack build on Linux ARM64  rather than Windows ARM64.
Becuase KleidiAI  doesn't support Windows

```
IF(XNNPACK_TARGET_PROCESSOR STREQUAL "arm64" AND XNNPACK_ENABLE_ARM_I8MM AND NOT CMAKE_C_COMPILER_ID STREQUAL "MSVC")
  IF (XNNPACK_ENABLE_KLEIDIAI)
    MESSAGE(STATUS "Enabling KleidiAI for Arm64")
  ENDIF()
ELSE()
  SET(XNNPACK_ENABLE_KLEIDIAI OFF)
ENDIF()
```
