Add QMK Compile Context Sensitivity (qmk#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 Co-Authored-By: skullydazed <skullydazed@users.noreply.github.com> * Shift config precedence to MILC Co-authored-by: skullydazed <skullydazed@users.noreply.github.com>

 ## `qmk flash`
 
 This command is similar to `qmk compile`, but can also target a bootloader. The bootloader is optional, and is set to `:flash` by default.
