ac4649da6e alif/tinyusb_port: Update dcd_init function to match TinyUSB v0.18.0.
These changes correspond to the following TinyUSB commits:

- d997f0071ea5d2d07e340d183fffb97e09526773
  change dcd_init() to take rhport struct

- 1f18be93db39dbc57bbf34f982dbe07e209a2ae3
  change the tusb_rhport_init_t struct, exclude the rhport to make API more
  consistent

- e83e08343afca86b2bacf26822ef9032571e6f56
  change dcd_init() return from void to bool

A fast host (eg Mac M4) may request the status for the SET_ADDRESS before
TinyUSB gets to process it.  This is because TinyUSB does not handle events
inside the USB ISR, rather it waits for the top-level thread to process
them.  Fix that by setting the USB device address as soon as
TUSB_REQ_SET_ADDRESS comes in.

This patch follows the corresponding upstream fix:
fc40ea7fc6

6b4d46569b alif: Support running the port on the HE core.
The same MicroPython firmware is built for the HE but with slightly
different options, for example no USB.

ccc5935234 alif: Add initial port to Alif Ensemble MCUs.
This commit adds the beginning of a new alif port with support for Alif
Ensemble MCUs.  See https://alifsemi.com/

Supported features of this port added by this commit:
- UART REPL.
- TinyUSB support, for REPL and MSC.
- Octal SPI flash support, for filesystem.
- machine.Pin support.

General notes about the port:
- It uses make, similar to other bare-metal ports here.
- The toolchain is the standard arm-none-eabi- toolchain.
- Flashing a board can be done using either the built-in serial bootloader,
  or JLink (both supported here).
- There are two required submodules (one for drivers/SDK, one for security
  tools), both of which are open source and on GitHub.
- No special hardware or software is needed for development, just a board
  connected over USB.

OpenMV have generously sponsored the development of this port.
