Subject: [PATCH] [Chore] (MG_Backend/Backends): Upgrade target OpenGL version
 to 3.3

* This is to align target OpenGL version with Minecraft 25w37a, which raised the minimum required OpenGL version to 3.3
* With this upgrade, the following features become part of the project's possible implementation scope:
  - Sampler Objects (ARB_sampler_objects)
  - Instanced arrays (ARB_instanced_arrays)
  - Explicit attribute locations (ARB_explicit_attrib_location)
  - Dual-source blending (ARB_blend_func_extended)
  - Timer queries (ARB_timer_query)
* These capabilities may be leveraged in future work depending on project needs
