feat(stm32mp2): add support for minimal FIP with only DDR FW

Load a minimal FIP used for DDR initialization for serial boot
when STM32MP_DDR_FIP_IO_STORAGE is activated.

This DDR FIP is loaded at the beginning of SYSRAM and used with
support of memmap features.

initialization when the function is called a second time.

On STM32MP25, this function is called 2 times, first to load FIP DDR
in small internal memory and after DDR initialization, to load FIP in
this large external memory

fix(st): replace down counter by a timeout upon dfu detach

On stm32mp2, DFU detach sometimes makes subsequent usb start to fail.
The core doesn't have the time to properly finalize the last setup
phase. This results in error logs seen:
ERROR: dwc3_handle_dev_event: 1688
ERROR: dwc3_handle_dev_event: 1692

Just enabling "DFU USB STOP" message hides the issue, sequentially:
usb_core_start()
...
usb_dfu_loop() // runs until DFU_DETACH command
--> while(it_count != 0U) {
usb_core_handle_it()
if (usb_dfu_detach_req)
it_count--; // down count from 100 to 0
}
...
INFO("DFU USB STOP...\n");
usb_core_stop()

The down-counter (it_count) value doesn't seem to be enough, and seems
not robust against CPU speed. So rather adopt a 100us timeout. It's
determined experimentally (above issue seems to be triggered around
20us to 30us, so keep some margin).

For a couple of releases now we have officially withdrawn support for
building TF-A on Windows using the native environment, relying instead
on POSIX emulation layers like MSYS2, Mingw64, Cygwin or WSL.

This change removes the remainder of the OS compatibility layer
entirely, and migrates the build system over to explicitly relying on a
POSIX environment.
