Set up initial page tables for both the offset-mapped area and the loaded kernel code and data. * Got rid of the `loaded_elf` struct - the loader now runs after the initial PML4 is created and maps the ELF sections itself. * Copied in the `page_table` and `page_table_indices` from the kernel, still need to clean this up and extract it into shared code. * Added `page_table_cache` to the kernel args to pass along free pages that can be used for initial page tables.
