Basically the integration code (cyw43_config.h and related implementations) are now in the driver.
cyw43_arch now just has
* async_context creation per CYW43_ARCH_TYPE
* pre-existing cyw43_arch methods for connect etc.
Add a general purpose random number generator via pico_rand library. which tries to use as much real entropy as possible mixed into a PRNG

This sets the compile-time flag for tinyusb's dcd_rp2040 driver by
default. Applications that won't ever be plugged into a Pi 4 or Pi 400
can optionally disable this.
* Remove (legacy) direct inclusion of 'pico/platform.h' which potentially skip config/board setup
* also fix direct use of pico/config.h which predated pico.h being assembly includable
* Extract all poll/threadsafe_background/freertos from cyw43_arch into new abstraction async_context:
* provides support for asynchronous events (timers/IRQ notifications) to be handled in a safe context.
* now guarantees all callbacks happen on a single core.
* is reusable by multiple different libraries (stdio_usb can now be ported to this but hasn't been yet).
* supports multiple independent instances (independent instances will not block each other).
* cyw43_arch libraries cleaned up to use the new abstraction. Note each distinct cyw43_arch type is now a very thin layer that creates the right type of context and adds cyw43_driver and lwip support as appropriate.
Additionally,
* Add new pico_time and hardware_alarm APIs
* Add from_us_since_boot()
* Add alarm_pool_create_with_unused_hardware_alarm()
* Add alarm_pool_add_alarm_at_force_in_context()
* Add hardware_alarm_claim_unused()
* Add hardware_alarm_force_irq()
* Added panic_compact() and some minor comment cleanup; moved FIRST_USER_IRQ define to platform_defs.h
* SYS functions and GCC 12 fixes
* Add implementation of _gettimeofday and settimeofday, _times
* Remove some GCC warnings about unimplemented SYS functions (e.g. _open) by making weak implementations that return errors.
* Removed _exit from crt0.S since we have a weak version in runtime.c and we don't want two weak impls since the linker can't pick. If the user omits runtime.c then they'll need to provide _exit or get the error
* Add sys/time.h to arch/cc.h for lwIP as it seems under GCC12 this is not getting included
In arm-gnu-toolchain-12.2 we see this warning, that's not relevant to
pico. Disable it.
warning: blink.elf has a LOAD segment with RWX permissions
Fixes#1029
fix bug #1068 where the raw irq handler that was added masked on IO_IRQ_BANK0 (defined as 13) and not the gpio connected to the CYW43 i.e. CYW43_PIN_WL_HOST_WAKE

* Added ARCHIVE_OUTPUT_DIRECTORY to uf2 output in CMake
This Commit enables the use of the ARCHIVE_OUTPUT_DIRECTORY target
properties in CMake for the generation of uf2 files.
The changeset in lines 47..51 is necessary due to CMake not
automatically creating the ARCHIVE_OUTPUT_DIRECTORY if no archive target
is present.
* rework cmake changes to make it friendler for non absolute paths

* Fix unexpected (CMake) behaviour with PICO_BOARD variable.
Changing PICO_BOARD value from "pico_w" to "pico" did not
unset PICO_CYW43_SUPPORTED variable. Which could lead
CYW43 driver included in builds for "pico".
solution: make PICO_CYW43_SUPPORTED a non cache variable
