Reverse operations are supported on stm32 and rp2, and esp32 has enough
space to also enable inplace operations, to make it complete.

This enables optional support for the hardware UART to use the RTS and/or
CTS pins for flow control.
The new "flow" constructor keyword specifies a bitmask of RTS and/or CTS.
This matches the interface used by machine.UART on stm32 and rp2.
Previously on ESP32 it was possible to specify which pins to use for the
RTS and CTS signals, but hardware flow control was never functional: CTS
was not checked before transmitting bytes, and RTS was always driven high
(signalling no buffer space available). With this patch, CTS and RTS both
operate as expected.
This also includes an update to the machine.UART documentation.

The QR decoder has a single item that is 8908 bytes big and placed
on the stack. (struct datastream)
Without enlarging the stack, this will reliably crash.
Call `supervisor.disable_ble_workflow()` and the BLE workflow will
be disabled until the chip is reset.
This also includes a couple fixes:
1. Terminals can now be deinit by setting the tilegrid to NULL. This
prevents using the tilegrid before display is init.
2. Fix BLE serial send amount when sending more than a single packet.

Hyperflash is used by the MIMXRT1050_EVKB, MIMXRT1060_EVK and
MIMXRT1064_EVK boards.
This commit includes:
- add support for Hyperflash
- modify MIMXRT1060_EVK and MIMXRT1064_EVK to change from QSPI to
hyperflash.
- minor incidental changes to other boards so they still build
Note: Erasing a sector on the hyperflash is slow. It takes about a second,
which seems too long, but matches the data sheet.
Add basic support for LEGO HUB NO.6 (e.g. LEGO SPIKE Prime, LEGO MINDSTORMS
Robot Inventor).
See README.md for details.
Thanks to @dpgeorge for helping put this together.

On ESP ctrl-c during fake sleep will now stop the sleep. A crash
on real deep sleep is now fixed as well. (Exception string saving
was crashing on reading the deep sleep exception.) Fixes#4010
This also fixes nRF fake sleep after the first time. The internal
variable wasn't being reset early enough. Fixes#4869
