Add C++ linting

[scotts]

Right now, we only use clang for formatting our C++ code:

torchcodec/.pre-commit-config.yaml

Lines 31 to 37 in 05a6ff5

	- repo: https://github.com/pre-commit/mirrors-clang-format
	rev: v18.1.3
	hooks:
	- id: clang-format
	name: clang-format
	files: \.(cpp|hpp|c|h)$
	types: [file]

We should also do some actual linting with clang as well.
