The bytecode state variables mp_showbc_code_start and mp_showbc_constants
have been removed and made local variables passed into the various
functions.
As part of this, the DECODE_PTR macro is fixed so it extracts the relevant
pointer from the child_table (a regression introduced in
f2040bfc7e).

This means that all constants for EMIT_ARG(load_const_obj, obj) are created
in the parser (rather than some in the compiler).

This commit adds generic support for mutable module attributes on built in
modules, by adding support for an optional hook function for module
attribute lookup. If a module wants to support additional attribute load/
store/delete (beyond what is in the constant, globals dict) then it should
add at the very end of its globals dict MP_MODULE_ATTR_DELEGATION_ENTRY().
This should point to a custom function which will handle any additional
attributes.
The mp_module_generic_attr() function is provided as a helper function for
additional attributes: it requires an array of qstrs (terminated in
MP_QSTRnull) and a corresponding array of objects (with a 1-1 mapping
between qstrs and objects). If the qstr is found in the array then the
corresponding object is loaded/stored/deleted.

All variants now use extmod/moduos.c as their uos module implementation.
In particular this means they all have MICROPY_VFS enabled and use VfsPosix
for their filesystem.
As part of this, the available functions in uos become more consistent with
other ports:
- coverage variant gets uos.urandom
- minimal and standard variant get: unlink, chdir, getcwd, listdir

Ensure the symmetry of PWM: the duty rate of X and Q channels was not 50%,
when it should have been. That is evident at high frequencies, like 15Mhz
or 37.5 MHz. At low frequencies the deviation mattered less. The A/B
channels were fine.
Also round up or down non-integer division factors. Before, always the
floor value was used.
That caused Ethernet to lock up at high data rates after ~200MByte data
average in a row. Tested now with data bursts up to 10 GByte and overall
data rates of ~8MByte/s at the Eth100 port.
Sometimes frames could not be sent immediately because the controller was
still busy with previous frames. Then, an error was returned to lwip.
This fix adds a limited number of retries for this busy state, waiting
100µs before the next attempt. Typically the transmit succeeds now at the
second attempt.
Second change: Reset the controller for a clean state after soft reset.
OCOTP_Init() has been removed from mphalport.c. The library files are
missing for the MIMXRT1015, and for just reading the OCOTP the Init is not
required.
The disk_access header was moved to a different path in Zephyr v2.6.0.
The old path was deprecated for two releases (v2.6.0 and v2.7.0) and
will no longer be supported after Zephyr v2.7.0.

This adds the "Not relevant" designation to PEP 486 since it has to do with
the Python Launcher for Windows and not the Python language itself.
Also fix a typo while we are touching this line.

If setting the frequency to a value used already by an existing timer, this
timer will be used. But still, the duty cycle for that channel may have to
be changed.
Fixes issues #8306 and #8345.
