Remove arch param where necessary

[0sewa0]

Description

DAQ-2193

Adds logic that it tries to define the most correct affinity for the deployed components.

• only "tries" because we can't be sure of what architectures does a "custom image" support, but we will assume that the a "custom image" is a replicated public registry image.

So from now on if the ActiveGate or the OneAgent images are from the tenant-registry then only the amd64 nodes are supported according to the affinity.

• This includes the "default scenario" (nothing is configured), and the "custom version" scenario (only a custom version is provided)

In all other cases ("custom image") we use the broader affinity, based on the public-registry images (amd64, arm64, ppc64le, s390x)

How can this be tested?

• Deploy OnaAgent and ActiveGate with default/custom-version ==> only amd64 in the affinity
• Deploy OnaAgent and ActiveGate with custom image ==> broader affinity used
  • images: public.ecr.aws/dynatrace/dynatrace-oneagent:1.303.55.20241122-143001, public.ecr.aws/dynatrace/dynatrace-activegate:1.303.25.20241118-125000
• Downloaded codemodules respect the architecture of the Operator image.
