WHY are these changes introduced?

The isWsl function performs a dynamic import and environment check every time it is called. This function is used during analytics reporting, which can happen multiple times during a single command execution. Memoizing the result improves efficiency by avoiding redundant work and imports.

WHAT is this pull request doing?

This PR memoizes the result of the isWsl function in packages/cli-kit. Subsequent calls will return the same promise instance, ensuring the underlying check only runs once.

Expected performance impact: Reduced overhead during analytics reporting and any other services that check for WSL status.

The `isWsl` function performs a dynamic import and environment check
every time it is called. Since the environment doesn't change during
the CLI execution, memoizing the result improves performance and
reduces overhead, especially during analytics reporting.
