feat: implement SwitchClause

[horw]

Implemented SwitchClause to enable the ability to use the following manifest format:

folder_foo:
  depends_components:
    - if: IDF_VERSION == "5.2.0":
      content: ["esp_eth"]
    - if: IDF_VERSION == "5.3.0":
      content: ["esp_wifi"]
    - default: ["esp_eth", "esp_wifi"]

or

folder_foo:
  depends_components:
    - esp_eth_1
    - esp_eth_2

closes #105

@hfudev Hi! I have updated the documentation for the switch statement. Please take a look

LGTM! Thanks for this nice feature.

left a few comments, and could you help add some tests on combining the depends_components+ together with the switch clauses?

[hfudev]

Cool. kudos to the nice test cases. LGTM!
