[QNN EP] Re-enable several disabled QNN-EP UTs (#23799)
### Description
1. Re-enable UTs which passed 2.30
2. Update resize UT because "round_prefer_floor" is no longer supported in QNN SDK since 2.21.
### Motivation and Context
1. Make the UT of QNN EP pass as much as possible to improve the test
coverage.
