This adds support for the Espressif ESP8266 and ESP32 devices to be used
as peripherals on a UART.
There are two main AT command versions that can be selected, 1.7 and
2.0. Since they behave a bit different it is important to select the
one that matches the used in the firmware on your device.
When downloading large amounts of data it is highly recommended to
enable CONFIG_ESP_PASSIVE_TCP and flow control on the UART so that
data is not lost due to UART speed or receive buffer size.
Currently unsupported:
- Changing UDP endpoint with a sendto()
- Bind to a specific local port
- Server socket operations, ie listen() and accept()

Switch to `NET_SOCKET_REGISTER` mechanism over the offloaded API
registration.
Including the following fixes from the review:
* The fd returned by the socket accept call needs to be finalized,
similar to how it is done for socket creation.
* sl_RecvFrom() in TI SimpleLink Host driver does not support NULL
pointers for 'from' address and address length, and sl_SendTo() does
not ignore the destination address when in connection mode, so passing
NULL would cause a failure. These issues have been reported to TI
(CC3X20SDK-1970, CC3X20SDK-1971).
Let's use sl_Recv and sl_Send to implement recvfrom/sendto in the case
of NULL addresses.
* simplelink_poll() should not process negative file descriptors in the
fds array after sl_Selecti() returns. A negative fd value indicates
that the entry is invalid and should be ignored.

Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).
Go for the most common style:
- Indent properties with a single tab, including for choices.
Properties on choices work exactly the same syntactically as
properties on symbols, so not sure how the no-indentation thing
happened.
- Indent help texts with a tab followed by two spaces
- Put a space between 'config' and the symbol name, not a tab. This
also helps when grepping for definitions.
- Do '# A comment' instead of '#A comment'
I tweaked Kconfiglib a bit to find most of the stuff.
Some help texts were reflowed to 79 columns with 'gq' in Vim as well,

These symbols appear within an 'if WIFI' (in drivers/wifi/Kconfig).
'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. Dependencies on menus work similarly. There are no
"conditional includes" in Kconfig, so 'if FOO' has no special meaning
around a source. Conditional includes wouldn't be possible, because an
if condition could include (directly or indirectly) forward references
to symbols not defined yet.
Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.
