[Lazarus] Possible Codetools issue for embedded targets in main branch

[Michael Ring]

While investigating further I suddenly saw that the unit was detected.

So I did a complete fresh install via fpcupdeluxe, opened a project for 
rp2040, saw the error.

Then I selected 'rescan fpc source directory' and the issue was gone.

So not sure if this is an issue or not, it definitely does not fully 
work as expected.
