[BuildCheck][Feature Request]: Make it possible to override the filename of EditorConfig

### Summary

The pr to support Editorconfig is out https://github.com/dotnet/msbuild/pull/9811 and in Review state.
Once merge I suggest to make it possible to override the file name that is used by the editorconfig parser (now it is .editorconfig)

### Background and Motivation

Motivation:

- Make feature more flexible in terms of configuration
- Specification does not require the file name to be ".editorconfig" but only it's format (https://spec.editorconfig.org/#terminology)
- In case we will face perf regression with already existing large .editorconfigs there will be a possibility to create a file configuring only for BuildCheck infra.

### Proposed Feature

Propose change:
Add command line switch: /analyzerConfig with key-value possibility
the first configuration to be presented is:
editorConfigFileName:""
