Logger: optional CR insertion for terminals without LF→CRLF handling

Component name

Describe the enhancement

Add an optional configuration flag to the logger component, for example:

logger:
  crlf_line_endings: true

When enabled, each \n sent on wire would be expanded to \r\n.

Use cases

Background

The logger component currently emits newlines using LF (\n) only, which is generally correct and expected.

However, some terminals do not interpret LF as a full newline (i.e., they do not perform carriage return). In such cases, log output becomes “staircased” because each new line starts at the previous cursor position.

This can be observed, for example, when using the Wokwi VS Code extension serial monitor, where LF does not imply CR. In contrast, early boot logs from ESP-IDF (e.g., bootloader output) appear correctly formatted, suggesting they use CRLF.

Anything else?

I already have a working local version of this change. Is it ok to share it?
Implementation is trivial (10 lines in write_to_console_ method ) and does not introduce memory overhead.
