Dear ImGui 1.87

[SpaiR]

Description

This PR updates Dear ImGui to v1.87 and ImPlot to v0.13. The ImPlot update was necessary due to broken compatibility with Dear ImGui v1.87.

Both updates introduce a significant amount of new API, so it's highly recommended to read the release notes for the original libraries.

Other Changes

• ImGuiImplGlfw and ImGuiImplGL3 have been synced with the versions from the v1.87 release. There are numerous changes on the GLFW side to adapt to the new IO API. Additionally, both backends have been re-written to be almost exact 1:1 copies of the original code. This will simplify future updates and reduce the likelihood of errors from missing components.
• Fixed an issue that prevented setting struct fields of the char * type.
• Corrected a problem where some Java-side structs did not call super in their constructors.

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
