[NDB PERMISSION_DENIED] Refactor _to_fuzzer_run_output to use FuzzerRunOutputData

[IvanBM18]

Bug: b/532610906

Context

• This PR comes as a need after the revert of this Revert "Fix legacy Datastore access in data_handler.py for UWORKERs" #5339 PR which introduced short circuit mechanisms to avoid DB queries, this however proved to provoke issues, so short circuit is no longer an option to fix any PERMISION_DENIED erros.
• There were 2 instances of PERMISSION_DENIED issues, the first one is already solved trough this [NDB PERMISSION_DENIED error] Fix trusty stacktrace on ANDROID_EMULATOR #5375

Overview

This Secons PR(Of 4) to tackle an instance of PERMISSION_DENIED issues when executing a BlackBox test case in a uworker bot.

This PR refactors the method that encapsulates the fuzzer output data into the results proto to use the new FuzzerRunOutput class, this way we can reuse the to_fuzzer_run_output() for both BlkacBox and Coverage guided fuzzing tasks

Changes

• to_fuzzer_run_output now accepts only a data class, instead of various parameters
