Subject: Add QMK Compile Context Sensitivity (#6884)

* Add context sensitive compile, without config check

* Initial full working state. Plan to refactor

* Refactor loop for simplicity, add comments

* Update docs/cli.md with qmk compile examples

* Simplify path for keyboard derivation

* Update path to use path.join instead of concat

* Refactor keyboard path, the skully way

* Add in keymap folder support

* Add /layouts compile support

* Update docs/cli.md with empty compile in layouts

* Add comments to compile.py

* Update docs for clarity, and fix compile error typo

* Fix config option compile

* Fix layout compile and failure mode

* Add rules.mk check

* Fix variable names for global config

* Add in_layout priority

* Remove default fallback in favor of throw, update docs

* Add keymap folder context

* Fix formatting

* Add os import

* Convert to create_make_command

* Fix Travis lint errors

* Remove blank line with whitespace

* Add blank lines for readability

* Remove unnecessary config logic

* Update Docs to add flash
