Enhance Room Plugin with Schema Export Support

[teogor]

This PR introduces the RoomOptionsExtension to configure schema export settings for the Android Room Convention Plugin. The RoomOptionsExtension allows you to fine-tune the behavior of schema export, which is essential for Room database auto migrations and version management.

Changes Made

• Added the RoomOptionsExtension to provide schema export configuration options.
• Enhanced the plugin to dynamically configure schema export settings based on the RoomOptions extension.

How to Use

To configure schema export, you can make use of the roomOptions extension in your build.gradle.kts or build.gradle files. For instance, by setting enableSchemaProvider = true, you enable schema export. You can also specify the directory where the schema files are stored using schemasPath. For example:

roomOptions {
  enableSchemaProvider = true
  schemasPath = "custom_schemas_directory"
}

This use case would enable schema export and set the schema directory to "custom_schemas_directory." It ensures that schema files are available for Room auto migrations and version management.

For more details and the benefits of schema export, please refer to the Room documentation on Exporting Schemas.
