Support generating STM32CubeIDE projects

**Is your feature request related to a problem? Please describe.**
I'd like to use the [STM32CubeIDE](https://www.st.com/en/development-tools/stm32cubeide.html) with my Mbed project.

**Describe the solution you'd like**
I'd like to use CMake to generate a STM32CubeIDE project.

**Describe alternatives you've considered**
I could try following [this community post about how to use a CMake project from STM32CubeIDE](https://community.st.com/s/question/0D53W00000S6Wiu/stm32cubeide-cmake-integration).

**Additional context**
None

Start by tracing how the existing Mbed command-line tooling generates CMake projects and compare its output with the STM32CubeIDE CMake integration described in the linked community post. Done means the tooling can generate a usable STM32CubeIDE project for an Mbed project and the generated project builds successfully in STM32CubeIDE.
