This adds support for CIRCUITPY_WIFI_SSID and CIRCUITPY_WIFI_PASSWORD
in `/.env`. When both are defined, CircuitPython will attempt to
connect to the network even when user code isn't running. If the
user code attempts to a network with the same SSID, it will return
immediately. Connecting to another SSID will disconnect from the
auto-connected network. If the user code initiates the connection,
then it will be shutdown after user code exits. (Should match <8
behavior.)
This PR also reworks the default displayio terminal. It now supports
a title bar TileGrid in addition to the (newly renamed) scroll area.
The default title bar is the top row of the display and is positioned
to the right of the Blinka logo when it is enabled. The scroll area
is now below the Blinka logo.
The Wi-Fi auto-connect code now uses the title bar to show its
state including the IP address when connected. It does this through
the "standard" OSC control sequence `ESC ] 0 ; <s> ESC \` where <s>
is the title bar string. This is commonly supported by terminals
so it should work over USB and UART as well.

Everything should be using the keypad module instead.
Note: there are several boards that still had gamepadshift enabled. I
did not contact their authors to make sure they already switched to
keypad in their code and documentation. We should probably wait with
merging this for their go ahead.
os.getenv() will use it (when available) to load variables from
/.env
This will also be useful when we need secrets or config for
CircuitPython outside of the VM (like WiFi credentials.)
Fixes#4212
This lets the BLE stack run through the wait period after a VM run
when it may be waiting for more writes due to an auto-reload.
User BLE functionality will have their events stopped. Scanning and
advertising is also stopped.
