[CI][aot] Do not overwrite scenarios argument if they were passed

[ilonatommy]

Continuation of switching off HybridGlobalization tests on v8. HybridGlobalization_AOT lane on CI was still running V8 because it was overwriting the scenarios argument passed here:

runtime/eng/pipelines/extra-platforms/runtime-extra-platforms-wasm.yml

Line 216 in e6c2e53

scenarios:

Example of run with v8 on:
https://dev.azure.com/dnceng-public/public/_build/results?buildId=702059&view=logs&j=2c5d15bf-ca52-57a8-9a4e-bb898fb954b8

Now we don't overwrite if scenarios is already defined.

@akoeplinger, most probably I have an indent/syntax problem that I cannot spot, could you please take a look?

[akoeplinger]

@ilonatommy it looks like some issue with the empty parameter: https://dev.azure.com/dnceng-public/public/_build/results?buildId=703502&view=results

is #51746, so we cannot enable running them yet, I will have to block HybridGlobalization_AOT till it's resolved. But generally the PR serves its purpose.
