fix infotext Lora hashes fro hires fix different lora

[w-e-w]

Description

there exist a minor flaw with infotext Lora hashes

currently the Lora hashes written to the infotext will be the Lora hashes of the "last last activated lores"
normally this works perfectly fine
the issue occurs when the using hires fix
as hires fix allows diffrent prompt which means the user can change the lora
if the uses removs some loras that are in the first pass then the Lora hashes infotext will not have the loras of the first pass obviously

---

this PR makes changes so it saves the lora hashes in saved in a dict under p.lora_hashes
when on first pass the dict will be set to empty {}
but is_hr_pass it will use the use the existing p.lora_hashes and add any new hashes to the dict

tested with the hires fix button and all seems to work fine

also compacted the code

---

TI hashes also have similar issues but and more
worse possibly due to where the code is it doesn't even write to infotext consistently
currently I not sure how to fix that, maybe someone who have an idea
