ImStrv: Step 2 - change ImStrv typedef to struct, perform all other logic conversion.

Browse Source 
Squashed commits (initially a commit from rokups + many rework by ocornut. keeping them separate commits made rebasing unnecessarily tricking so merged from 2024/02)
ImStrv: many fixes (see details), added imconfig class extension example, added natvis description.
ImStrv: rework toward ensuring End is always set to constant can be compile time calculated
ImStrv: using length(), fix ambiguous empty() function, fix altered behaviors, removed unused operators.
ImStrv: various tweaks and fixes. removed ImGuiTextRange from ImGuiTextFilter, fix test engine hooks, removed constructor only used twice.

//---- Use 32-bit vertex indices (default is 16-bit) is one way to allow large meshes with more than 64K vertices.
// Your renderer backend will need to support it (most example renderer backends support both 16/32-bit indices).
// Another way to allow large meshes while keeping 16-bit indices is to handle ImDrawCmd::VtxOffset in your renderer.
