Remove shader compilation code from audio example
remove PBDFluid benchmarking example

Also enforces formatting

Use already defined enums as arguments

CLEANUP: added ability to expand surface meshes, abstracted interactor, and fixed transforms in Vulkan renderer

Add audio testing examples in sandbox. Add resources to the data folder

The reset doesn't work for NeoHookean PBD constraints but works
for other types of constraints. This is added to issue tracker.

Using StVK type FEM constraint in PBDVolume() example

Some format enforcements by Uncrustify

1. Enables correct winding of the surface
triangles of the surface mesh extracted from the
tetrahedral mesh
2. Adds render material for the surface mesh
3. Change the default mesh that is loaded in the sandbox example

Adds option to start the simulation manager with
the simulation either in RUNNING or PAUSED mode
and the viewer in DEBUG or SIMULATION mode.

Other changes:
1. enforce const correctness
2. add comments to the member functions
3. add overload function to retrieve scene manager by scene object
4. rename 'current' scene to 'active' scene
