feat(cmakev2/size): add idf_create_size_report function

The idf_create_size_report function allows for the creation of size
report targets based on the generated link map file. The size report
targets are created using the TARGET option name: "<target>",
"<target>-files", and "<target>-components". These size report targets
are added to the idf_default_project with the TARGET set to "size",
resulting in the creation of "size", "size-files", and "size-components"
targets for the default project.
