Revisit debug symbols being picked up for upload

[bitsandfoxes]

Came up here: #654 (comment)

When using the burst compiler it creates some additional debug symbol files that should be uploaded.

• ProjectName_BurstDebugInformation_DoNotShip
• lib_burst_generated.pdb

Maybe we should do it in a more generic manner and upload all .pdb files under the app directory. Maybe including .dlls as well

[bitsandfoxes]

Especially the "all .dlls as well is relevant now. I'm running into that with baselib.dll.
