Fix: [CI] don't install breakpad on arm64-windows-static, as it is not supported (yet)

[TrueBrain]

Motivation / Problem

Nightlies currently fail, as breakpad doesn't support Windows ARM64. Sad times.

Description

In theory we could fall back to dbghelp.dll, but honestly, I don't think there are many users of Windows ARM64 atm. So that is effort without any real possibility to test if it is functional. So currently, we just disable minidumps on Windows ARM64. The rest of the reporting still happens. Just no minidump.
