Update bun.d.ts with BuildPlatform and BuildArchitecture types

This commit adds support for the `compile: boolean | "${platform}-${arch}"` option in `Bun.build` by:

1. Adding new BuildPlatform and BuildArchitecture type definitions
2. Creating a BuildTarget type that supports various formats
3. Updating the BuildConfig interface with separate compile and targets options
4. Adding comprehensive tests for the compile functionality

This addresses part of the PR requirements and makes the API more flexible
and future-proof by supporting multiple target formats.
