Moved and renamed files for consistent C code style (#463)

* **Documentation**
  * Added new C coding style guide detailing naming conventions for files, directories, macros, constants, variables, functions, and type definitions with illustrative examples.
  * Updated C++ coding style documentation with clarifications on C naming conventions and header directory organization patterns.

* **Refactor**
  * Updated header include paths throughout the codebase to use lowercase naming conventions consistently.
