[QNN EP] Update Windows ARM64 pipeline to use Visual Studio 2022 (#15607)
### Description
- Updates the QNN Windows ARM64 pipeline to use a new image with Visual
Studio 2022 (updated from VS 2019)
- Creates a new gtest fixture class that skips tests for the QNN CPU
backend if we detect that the QNN CPU backend is not
available/functional. The current windows arm64 vm does not support any
QNN backend.
### Motivation and Context
Visual Studio 2022 adds support for native arm64 compilation. This
pipeline will help catch any build regressions on Windows ARM64 w/ VS
2022.
