Rearrange the file layout in preparation of becoming a monorepo

Move the documentation to `doc/plugin/HostPowerManagement.md`, sources under
`src/kaleidoscope/plugin/` (appropriately namespaced). This is in preparation of
merging plugins into a single monorepo.

-## Using the plugin
-
-To use the plugin, one needs to include the header, and activate it. No further
-configuration is necessary, unless one wants to perform custom actions.
-
-```c++
-#include <Kaleidoscope.h>
-#include <Kaleidoscope-HostPowerManagement.h>
-
-KALEIDOSCOPE_INIT_PLUGINS(HostPowerManagement);
-
-void setup () {
-  Kaleidoscope.setup ();
-}
-```

-## Plugin methods
-
-The plugin provides the `HostPowerManagement` object, with no public methods.
-
-## Overrideable methods
-
-### `hostPowerManagementEventHandler(event)`
-
-> The `hostPowerManagementEventHandler` method is the brain of the plugin: this function
-> tells it what action to perform in response to the various events.
->
-> Currently supported events are: `kaleidoscope::HostPowerManagement::Suspend` is fired
-> once when the host suspends; `kaleidoscope::HostPowerManagement::Sleep` is fired every
-> cycle while the host is suspended; `kaleidoscope::HostPowerManagement::Resume` is
-> fired once when the host wakes up.
->
-> The default implementation is empty.

-Starting from the [example][plugin:example] is the recommended way of getting
-started with the plugin.
