c0152e7dab Remove gamepadshift module 
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.

Enable squeezing property storage in flash 
.. and enable it on atmel-samd and raspberrypi. On trinket_m0 this saves
96 net bytes of flash. There are 216 bytes actually saved by reducing
the flash storage size of the property descriptors, but added code in
several paths takes back over half of the 'raw savings'.

By organizing the "get-only" and "get-set" (but no delete) properties
each in a different section, we can represent then more efficiently.

Testing performed: that a get-only property can still be gotten but
can't be set or deleted; that a get-set property can sill be gotten or
set but can't be deleted.  Tested on pygamer.

Because this requires linker file support, I only enabled it on two of
the ports.

samd: Don't rely on RTC interrupt 
I instrumented RTC_Handler and determined that on SAMD51 it was possible
for the interrupt to be delivered well before the actual overflow of the
RTC COUNT register (e.g., a value as small as 0xffff_fffd could be seen
at the time of overflow)

Rather than depending on the overflow interrupt coming in at the same time
as COUNT overflows (exactly), rely only on observed values of COUNT in
_get_count, overflowing when it wraps around from a high value to a low
one.

With this change, PLUS a second change so that it is possible to warp
the RTC counter close to an overflow and test in 20ms instead of 3 days,
there was no problem detected over 20000+ overflows. Before, a substantial
fraction (much greater than 10%) of overflows failed.

Fixes #5985

Change to common-hal/rtc/RTC.c for time warping (plus make rtc_old_count non-static):
```patch
 void common_hal_rtc_set_calibration(int calibration) {
+
+    common_hal_mcu_disable_interrupts();
+
+        RTC->MODE0.COUNT.reg = 0xffffff00;
+        rtc_old_count = 0;
+        do {
+        while ((RTC->MODE0.SYNCBUSY.reg & (RTC_MODE0_SYNCBUSY_COUNTSYNC | RTC_MODE0_SYNCBUSY_COUNT)) != 0) { }
+    }
+    while(RTC->MODE0.COUNT.reg < 0xffffff00);
+    common_hal_mcu_enable_interrupts();
+
+    mp_printf(&mp_plat_print, "Warping RTC in calibration setter count=%08x rtc_old_count=%08x\n", RTC->MODE0.COUNT.reg, rtc_old_count);
```

Test program:
```python
import time
from rtc import RTC

i = 0
while True:
    RTC().calibration = 1 # Warps to ~16ms before overflow, with patch to RTC code
    t0 = time.monotonic_ns()
    et = t0 + 20_000_000 # 20ms
    while (t1 := time.monotonic_ns()) < et: pass
    i += 1
    print(f"{i:6d}: duration {t1-t0}")
    if t1-t0 > 200_000_000: break
    print()
```

Improve the USB vid:pid duplicate checker 
To me, it made more sense to track which boards go together in a cluster;
when reviewing a request to actually use a duplicate vid/pid, you want
to know what board(s) it is aliasing.

I also revamped the detection of non-USB boards so that a board .mk file
that couldn't be parsed by the code here would raise a problem instead
of just being skipped for the purposes of checking.

There were some lines with comments on the end, and some variation in
capitalization of the IDs. These are all normalized and a (sometimes
unfriendly!) error printed when it's incorrect.

Before this, here were some ways to trick the duplicate vid/pid checker:
```
USB_PID = 0XABCD
USB_PID = 0xAbCd
USB_PID = 0xABCD # harmless comment?
```
None of these things were ever done on purpose.

Board definition clean up 
Removes:
* AUTORESET_DELAY_MS which never did anything but was introduced
  somehow.
* CIRCUITPY_BOOT_BUTTON in all but one ESP board because they all have
  them. There is a default based on the strapping pins.
* BOARD_USER_SAFE_MODE_ACTION because it was all the same for boards
  with boot buttons. Now the safe mode code manages the message.

93ea1bd9bd Add a flag for removing the Blinka logo from the REPL 
There may be several reasons why we might want to remove the logo form
the REPL: a fork of CircuitPython that doesn't have the right to use the
logo, an especially small display that needs all the room it has to be
useful, displays that are especially vulnerable to burn-in, maybe even
the smaller chips where we want to save as much flash memory as
possible.

disable onewireio on seeduino xiao (samd21) 
I don't understand how this stopped fitting, as none of the added code
is used in this build.

ESP NeoPixel fixes 
This tweaks the RMT timing to better match the 1/3 and 2/3 of 800khz
guideline for timing. It also ensures a delay of 300 microseconds
with the line low before reset.

Pin reset is now changed to the IDF default which pulls the pin up
rather than CircuitPython's old behavior of floating the pin.

Fixes #5679

Add floppyio 
Initially enabled for samd51, this enables reading raw flux data as well
as DOS/MFM formatted media.

This is only the low-level code for reading & decoding flux pulses from a floppy drive.
high level details will live in a Python library.

adafruit-circuitpython-floppy will take care of details like stepping
from track to track, etc.

Add a function to get low level register access 
The port is free to return NULL for any/all of these, and the caller has
to check.

This will be used in the floppy code, because aside from getting the
registers, it looks like all is independent of MCU.
