roll: pigweed targets/rp2040: Add default linker script targets

Add rp2040_linker_script and rp2350_linker_script targets which
depend on the pico-sdk default linker script for now.

Next step is to update downstream projects to reference these
targets.

Finally, http://pwrev.dev/234155 will modify these targets to use
the custom linker script.
