feat: install system-images

[itsspriyansh]

Description

This PR:

• Introduces a streamlined way to download system images. Instead of overwhelming users with all options at once, we present an intuitive, step-by-step selection process. Users will start by choosing an API level, then proceed to select the type for that level, and finally pick the architecture. Once all selections are made, the download will begin automatically. This user-friendly approach ensures a smooth and efficient experience.
• Adds a new spawnCommandSync to install system images. This is done to show the installation progress bar to the user. The logic is put in utils/sdk.ts since it will be common function for both installing system images and running dot commands.

PR #56 adds the index.ts file from which we will call the script in this PR. Once both these PRs are merged then we can add the functionality to call this script.

Where's the "System image already downloaded" statement coming from as shown in the video?

Where's the "System image already downloaded" statement coming from as shown in the video?

@garg3133 That is older video. Since we are using spawnSync now, we aren't capturing the output anymore. So everytime the command is run (irrespective of system image being previously installed or not) we will get the same output "System image installed successfully!". Does this work or shall we remove the message entirely since we are already showing the CLI output by sdkmanager?
