scobert969 7bbfe99fbe Add on-screen keyboard to InkHUD (#9445)
* Added keyboard option to menu. Shows a keyboard layout but does not type.

* Keyboard types into text box and wraps.

* send FreeText messages from the send submenu

- renamed `KEYBOARD` action to `FREE_TEXT` and moved its menu location
to the send submenu
- opening the FreeText applet from the menu keeps the menu open and
disabled the timeout
- the FreeText applet writes to inkhud->freetext
- the sending a canned message checks inkhud->freetext and if it isn't
empty, sends and clears the inkhud->freetext

* Text scrolls along with input

* handle free text message completion as an event

implements `handleFreeText` and `OnFreeText()` for system applets to
interface with the FreeText Applet

The FreeText Applet generates an `OnFreeText` event when completing a
message which is handled by the first system applet with the
`handleFreeText` flag set to true.

The Menu Applet now handles this event.

* call `onFreeText` whenever the FreeText Applet exits

allows the menu to consistently restart its auto-close timeout

* Add text cursor

* Change UI to remove the header and make text box longer
Keyboard displays captial letters for legibility
Keyboard types captial letters with long press

* center FreeText keys and draw symbolic buttons

Move input field and keyboard drawing to their own functions:
- `drawInputField()`
- `drawKeyboard()`

Store the keys in a 1-dimensional array

Implement a matching array, `keyWidths`, to set key widths relative to
the font size

* Add character limit and counter

* Fix softlock when hitting character limit

* Move text box as its own menu page

* rework FreeTextApplet into KeyboardApplet

- The Keyboard Applet renders an on-screen keyboard at the lower portion
of the screen.
- Calling `inkhud->openKeyboard()` sends all the user applets to the
background and resizes the first system applet with `handleFreeText` set
to True to fit above the on-screen keyboard
- `inkhud->closeKeyboard()` reverses this layout change

* Fix input box rendering and add character limit to menu free text

* remove FREE_TEXT menu page and use the FREE_TEXT menu action solely

* force update when changing the free text message

* reorganize KeyboardApplet

- add comments after each row of `key[]` and `keyWidths[]` to preserve
formatting

- The selected key is now set using the key index directly

- rowWidths are pre-calculated in the KeyboardApplet constructor

- removed `drawKeyboard()` and implemented `drawKeyLabel()`

* implement `Renderer::clearTile()` to clear the region below a tile

* add parameter to forceUpdate() for re-rendering the full screen

setting the `all` parameter to true in `inkhud->forceUpdate()` now
causes the full screen buffer to clear an re-render. This is helpful for
when sending applets to the background and the UI needs a clean canvas.

System Applets can now set the `alwaysRender` flag true which causes it
to re-render on every screen update. This is set to true in the Battery
Icon Applet.

* clean up tile clearing loops

* implement dirty rendering to let applets draw over their previous render

- `Applet::requestUpdate()` now has an optional flag to keep the old
canvas

- If honored, the renderer calls `render(true)` which runs
`onDirtyRender()` instead of `onRender()` for said applet

- The renderer will not call a dirty render if the full screen is
getting re-rendered

* simplify arithmetic in clearTile for better understanding

* combine Applet::onRender() and Applet::onDirtyRender() into Applet::onRender(bool full)

- add new `full` parameter to onRender() in every applet. This parameter
can be ignored by most applets.

- `Applet::requestUpdate()` has an optional flag that requests a full
render by default

* implement tile and partial rendering in KeyboardApplet

* add comment for drawKeyLabel()

* improve clarity of byte operations in clearTile()

* remove typo and commented code

* fix inaccurate comments

* add null check to openKeyboard() and closeKeyboard()
