Optimize input note num inputs/assets memory layout

After #2109 is closed (to avoid merge conflicts), we should be able to make a tiny PR that moves these two constants closer together:

https://github.com/0xMiden/miden-base/blob/eee0e8450b825857e7d56ffebfaa269378a61aca/crates/miden-protocol/src/transaction/kernel/memory.rs#L388-L389

It should be possible to do:

pub const INPUT_NOTE_NUM_INPUTS_OFFSET: MemoryOffset = 36;
pub const INPUT_NOTE_NUM_ASSETS_OFFSET: MemoryOffset = 37;
pub const INPUT_NOTE_ASSETS_OFFSET: MemoryOffset = 40

This applies to memory.masm in the same way.
