This commit simplifies the customisation of the main MicroPython execution
loop (4 macros are reduced to 2), and allows a board to have full control
over the execution (or not) of boot.py and main.py.
For boards that use the default start-up code, there is no functional
change in this commit.

This update to the PR retains the earlier board rev (with a rename) so
that backward binary compatibility is not lost for the earlier board
revision. The primary name 'vina-d51' is retained for the latest
revision to make it easy for customers to select the proper UF2
download - because the name matches the commercial name.
Details:
Replace bdmicro_vina_d51 with bdmicro_vina_d51_pcb7 (revision 7 of
PCB) with boardfiles unmodified. Add _pcb7 to the workflow build.
Replace bdmicro_vina_d51 boardfile content with latest PCB updates
(revision 10 ov PCB). Add minimal comments in the board files to make
it clear which PCB revision is implemented. Update the USB PID to
reflect an updated board revision.
Per CPython everything which comes after the command, module or file
argument is not an option for the interpreter itself. Hence the processing
of options should stop when encountering those, and the remainder be passed
as sys.argv. Note the latter was already the case for a module or file but
not for a command.
This fixes issues like 'micropython myfile.py -h' showing the help and
exiting instead of passing '-h' as sys.argv[1], likewise for
'-X <something>' being treated as a special option no matter where it
occurs on the command line.
Some forum users noticed that `sm.exec()` took longer the more was present
on the flash filesystem connected to the RP2040. They traced this back to
the `array` import inside `asm_pio()`, which is causing MicroPython to scan
the filesystem.
uarray is a built-in module, so importing it shouldn't require scanning the
filesystem.
We avoid moving the import to the top-level in order to keep the namespace
clean; we don't want to accidentally expose `rp2.array`.
Support for C++ was added in 97960dc7deb7a0e691fca5944402cd03386b744b but
that commit didn't include the C++ exception handling table in the binary
firmware image. This commit fixes that.

This is a workaround for errata RP2040-E5, and is needed to make USB more
reliable on certain USB ports.

ESP-01 header renamed to AUX, and expanded to 12 pins from 8
pins. Pins 1-8 still accommodate the ESP-01, with expansion to full
SERCOM 4-pad support to allow for SPI and I2C on that expansion port
with additional GPIO control.
Update pins.c with additional signals provided AUX_1-8, along with
UART, SPI, I2C name usage as aliases to appropriate AUX_1-8
signals. Additionally, add several alternate names specific to several
expansion modules - the ESP-01, and the ATW-01 using the WINC_1500
(SPI) w/interrupt and control needed for the WINC - with assignments
to module pin positions.
Re-work SERCOM assignments to accommodate the above from other parts
of the board, which required moving a SERCOM or two around in order to
accommodate the 4-pad sercom pin mapping on the AUX port.
Built and tested using latest from 'main':
