[cbuild] Add option to setup command allowing it to run without installed toolchains

[brondani]

The cbuild setup has multiple goals and one of them is to generate compile_commands.json: this feature requires the presence of CMake and installed toolchains.
To allow the use of others features, such as the layer detection mechanism, the cbuild setup should have an option to run only the first orchestration of csolution calls, avoiding orchestration of CMake and subsequently toolchain calls.
This is particularly important for online IDEs and services where the project management is fully decoupled from build management.
Suggestion for the option: --no-database

@brondani @jkrech
I've come up with a few additional options, including the one initially suggested. Do you have any preference or perhaps a better suggestion for naming the option, as well as for its short description?

• --no-cmake Skips CMake orchestration and toolchain setup, focusing only on project management
• --skip-build-orchestration Avoids orchestration of both CMake and toolchains, running only the initial project setup calls
• --no-database Executes only the project management phase of project orchestration without triggering CMake
• --no-toolchain Disables the orchestration of toolchains and CMake, limiting execution to project setup steps

--no-database Skips the generation of compile_commands.json files
