perf-pipeline: Remove unnecessary jobs (dotnet#76111)

* perf-pipeline: Set default value for ExtraSetupArguments

Fixes `line 1: ExtraSetupArguments: command not found` when running
performance/scripts/ci_setup.py .

* perf pipeline: Disable unncessary scheduled builds

`dotnet-runtime-perf` runs:
1. batched builds
2. scheduled builds at 2:30am every night

For the 'scheduled' case, only wasm/jsc perf jobs are run.
And the rest are build jobs - wasm, mono, coreclr, and libraries.

The wasm/jsc runs are known to be broken right now, thus they can be
disabled. And since there are no other perf jobs, none of the remaining
builds are needed, thus the whole scheduled run can be disabled.

* perf-pipeline: Collect logs file from perf runs on dotnet-runtime-perf also
