Constant mmtk::util::malloc::library::BYTES_IN_MALLOC_PAGE

pub const BYTES_IN_MALLOC_PAGE: usize = _; // 4_096usize

When we count page usage of library malloc, we assume they allocate in pages. For some malloc implementations, they may use a larger page (e.g. mimalloc’s 64K page). For libraries that we are not sure, we assume they use normal 4k pages.
