There are a number of internal headers local to mm/ which reference functions and data types without including the relevant headers. mm/vma.h is a special case that intentionally does not include additional headers, but the others are not. This breaks tooling like clangd (which is where I noticed this), though the build is OK due to the C files including the headers happening to include required dependencies. It's better to be explicit about dependencies anyway, so add the missing includes and fix clangd as a bonus.
