Unify iMX flash config and add Metro M7 1011
This unifies the flash config to the settings used by the Boot ROM.
This makes the config unique per board which allows for changing
quad enable and status bit differences per flash device. It also
allows for timing differences due to the board layout.

This change also tweaks linker layout to leave more ram space for
the CircuitPython heap.

Split pulseio.PWMOut into pwmio
This gives us better granularity when implementing new ports because
PWMOut is commonly implemented before PulseIn and PulseOut.

Fixes #3211

a580f0f1c4 _pew: move to common-hal
I noticed that this code was referring to samd-specific functionality,
and isn't enabled except in one samd board (pewpew10).  Move it.

There is incomplte support for _pew in mimxrt10xx which then caused build
errors; adding a #if guard to check for _pew being enabled fixes it.
The _pew module is not likely to be important on mimxrt but I'll leave the
choice to remove it to someone else.

dd5d7c86d2 Fix up end of file and trailing whitespace.
This can be enforced by pre-commit, but correct it separately to make it easier to review.

Enable SNVS interrupt
The iMX RT has a separate wake up controller, the GPC, that replaces
the NVIC when asleep. It adds the ability to only wake up on certain
interrupts. It seems that it requires at least one enabled interrupt
in the NVIC to turn on it's wake up circuitry. It doesn't need to
be the same interrupt as the wake up signal. For example, the RTC
in the SNVS can wake us up if a USB interrupt is enabled. Before
then it won't work. So, we enable the SNVS interrupt on start up
so it can wake us up.

Fix start on power up by providing Reset_Handler ourselves.
On power up the FlexRAM banks are in an unknown config so we can't
rely on the stack until after we configure FlexRAM.

Refine iMX RT memory layout and add three boards
Introduces a way to place CircuitPython code and data into
tightly coupled memory (TCM) which is accessible by the CPU in a
single cycle. It also frees up room in the corresponding cache for
intermittent data. Loading from external flash is slow!

The data cache is also now enabled.

Adds support for the iMX RT 1021 chip. Adds three new boards:
* iMX RT 1020 EVK
* iMX RT 1060 EVK
* Teensy 4.0

Related to #2492, #2472 and #2477. Fixes #2475.
