Proposal: Allow simplified process filter schema

[jander-msft]

The current process filter schema allows for setting a key and a value and an optional match type, for example:

{
  "Key": "ProcessName",
  "Value": "dotnet"
}

This can be simplified to:

{
  "ProcessName": "dotnet"
}

in order to help minimize the verbosity.

Proposed Change

Add ProcessName, ProcessId, and CommandLine properties to the process filter descriptor in order to help minimize the verbosity of the configuration. The underlying transform can then check if the values are pulled from these new properties or from the Key/Value properties.
