cbuild --clean should not print warnings about configuration mistakes

The Problem To Be Solved

I don't think that cbuild with option --clean should output warnings about configuration mistakes. It does not feel right.

An output example (of a converted solution) using the new MDK Middleware pack:

C:\Test\Blinky-LPC1700\Boards\Keil\MCB1700\Blinky>cbuild Blinky.csolution.yml --clean
warning csolution: 'Blinky_Release.sct' this linker script is ignored; multiple linker scripts defined

Cleaning is a two-step process.

1. The first step involves generating build files such as cbuild-idx.yml and cbuild.yml. These files provide information on the directories that need to be cleaned.
2. The second step is to perform the cleaning, using the directory information gathered in the first step.

Therefore, the warnings seen during the cleaning process are due to the dependency of the second step on the successful generation of these build files.

I'm unsure if clean should be that clever.

We have a few other issues that are related:

• Clean does not work for multitarget projects #1809
• cbuild rebuild fails after context-set has changed #1801
• When changing the number of execute: nodes, a CMake error is output. #1757
• Trigger rebuild on changes to cbuild-set.yml #1813

Let's have a discussion next week.
