[test] refactor common test target settings (#27013)

### Description
- factor duplicated test target settings into helper functions
- reuse helpers for onnxruntime_test_all and onnxruntime_provider_test
- keep target-specific settings intact


### Motivation and Context

There are some duplicated codes in the onnxruntime_unittests. Originally
there is only one unit test `onnxruntime_test_all` and later it is split
into two: `onnxruntime_test_all` and `onnxruntime_provider_test`. Some
lines for setting up build flags are simply copied. This causes
potential risk for inconsistency in future.
