Add the remaining AMX intrinsics

[sayantn]

As rust-lang/rust#155264 is now merged, we can finally implement the __tile1024i AMX intrinsics.

Currently draft because I am still unsure of what should be the API of __tile1024i -- the current design is very cumbersome to use. To load a tile from memory, the code looks like

let mut tile = MaybeUninit::uninit();

let tile_ptr = tile.as_mut_ptr();

(*tile_ptr).rows = rows;
(*tile_ptr).cols = cols;
__tile_loadd(tile_ptr, mem_addr, stride);

let tile = tile.assume_init();

So it might be useful to provide at least 1 function that just sets the rows and cols fields and returns the MaybeUninit.
