REVIEWED: rcamera module formating
REVIEWED: `core_3d_camera_example`

It was quite restrictive and hacky implementation, just load multiple types same sound to play multiple instances.

Changes the DLL export condition to apply to platform WIN32 instead of
compiler MSVC

Some format tweaks

It shouldn't matter much but it could avoid some conflicts with other libraries in the future (like `tinyfiledialogs`).

Reordered some functions to avoid config.h issues when disabling some features.

* Use RL_QUADS/RL_TRIANGLES for single-pixel drawing

Addresses problem mentioned in
https://github.com/raysan5/raylib/issues/2744#issuecomment-1273568263
(in short: when drawing pixels using DrawPixel{,V} in camera mode,
upscaled pixel becomes a line instead of bigger pixel)

* [rtextures] Fixed scaling down in ImageTextEx

Closes #2755
