[QNN EP] Always write to profiling file if `profiling_file_path` is given. (#24781)
### Description
<!-- Describe your changes. -->
Always write to profiling file if `profiling_file_path` is given.
### Motivation and Context
<!-- - Why is this change required? What problem does it solve?

Previously, on Windows, if the ETW path is enabled, the profiling data
will not be written to the file even if `profiling_file_path` is given.
I thought that this behavior was confusing.
