Added some doxygen documentation to TextureEnumBase.h and TextureManager.h

removed textures map from AssetManager as it is no longer used.
Updated SpriteComponent to now check if it is a normal Texture or a MapTileTexture.
Added if condition in TextureManager::LoadMapTileTexture to check if the texture was able to be loaded by SDL

+ * types in their own implementation, providing flexibility in texture management within the engine.
+ *
+ * \details
+ * The \c Textures enum class is intended to be implemented by the developer within their own scope.
+ * This allows for customized texture entries to be defined based on the specific needs of the project.
+ * The base declaration ensures that the enum class can be referenced and used consistently throughout

+ * \class TextureManager
+ * \brief A manager for loading, caching, and drawing textures.
+ *
+ * The `TextureManager` class is responsible for handling texture loading, caching,
+ * and rendering in the engine. It provides functions to add, load, and draw textures
+ * from files, as well as manage sprite sheets.
+ *
+ * It uses two caches: one for regular textures (`texture_cache`) and one for
+ * map tile textures (`mapTile_texture_cache`). This allows for efficient texture reuse
+ * and management across different parts of the game.
+ *
+ * \note Textures are identified by an enum class `Textures` which is user-defined.
+ *       Developers are expected to define the texture types in their own implementation.
