No changes were made to the Bazel environment as this appears to be more complicated (and a brand new area for me) and I'd rather not invest the time without knowing if this approach is going to be acceptable. |

The 'host' platform only really partially simulates an RP2040 environment, with no way to specify a particular board either, so attempting to build a host version of a existing code that uses an RP2350 or relies on values defined in a board file is either difficult or impossible. Instead of setting PICO_PLATFORM to just 'host', it can now be set to 'host-rp2040' or 'host-rp2350' and PICO_BOARD can be set to any board configuration that is compatible with the given chip type. Platform definitions for the given chip will be fetched, meaning defines such as 'NUM_IRQS' will be set correctly. Fixes raspberrypi#2778

Fixes #2778
Note that some changes are needed to the
picotoolrepository when building for a genuinerp2350target as it does not initialise the pico-sdk completely and so will fail to findplatform_defs.h.
