Incorrect relative local library dependency path resolution when sketch file path used as argument

[sparkyb]

Describe the problem

In a sketch.yaml profile, you can specify local libraries as dir: <LOCAL_LIB_PATH> (#2930). According to the documentation, "The path could be absolute or relative to the sketch folder." This works correctly if you just run arduino-cli compile from inside the sketch folder or if you pass a path to the sketch folder like arduino-cli compile Sketch. But if you specify the sketch filename on the command line like arduino-cli compile Sketch/Sketch.ino, then it interprets local library paths relative to this sketch file instead of the sketch folder.

To reproduce

1. Create a project folder.
2. Within that, create a Libraries/TestLib folder with a TestLib.h and TestLib.cpp in it.
3. In the project folder, also create a Sketch/Sketch.ino file that has #include <TestLib.h>
4. Create Sketch/sketch.yaml that has a default profile that includes in its libraries: section dir: ../Libraries/TestLib
5. From the project folder, run arduino-cli compile Sketch. This will work.
6. From the project folder, run ardunio-cli compile Sketch/Sketch.ino. This will fail with the error message: Error initializing instance: Invalid library directory in sketch project: ../Libraries/TestLib
7. If you changed the library path in sketch.yaml to dir: ../../Libraries/TestLib and then run the command in step 6 it will work, but now the command from step 5 won't.

Expected behavior

My expectation is that the filename should be stripped if specified and relative paths should always be relative to the folder whether a file is specified or not. The library path should be dir: ../Libraries/TestLib and work in both steps 5 and 6.
