Does someone know the origin and reason for that shrill scream sound made by Sephardim at Simchos?
The “shrill scream to which you refer has a name. In English, it’s called ululation and it is common for festivities in Arab and other Middle Eastern cultures.
Did Sephardim ever discontinue permitting having multiple wives (other than when moving to countries where secular law prevented it)? If so, which and when?
It’s called a ululation. I am guessing it is borrowed from the local Arab culture in which they lived?
Daas zekeinim says it’s from yaakov avinus wedding
People we’re yelling “hee Leah hee Leah”
Rabbi Ben tzion Shaifer from “the shmuz” says in one of his lectures, quoting the Daas zekeinim mibaalei tosfos that it’s meant to be saying “hee Leah” she’s Leah. Commemorating Yaakov and Leah s wedding where people did tried using that sound to hint that it’s really Leah and not Rochell
Did anyone hear that it’s to scare off the Ayin Harah?
I wouldn’t look too deeply in it. It’s like clapping. We wouldn’t make such a chakira on clapping. So hu hadin by ululations… It’s simply a Middle Eastern form of happiness.
Sephardim as a group didn’t officially ever discontinue polygamy although the level of prevalence has varied. In some Sephardic communities it prob didn’t really exist at least not over the last 200 yrs or so
Regarding marrying more than one wife. In my community the minhag is to put this restriction as a tnai in the ketuva: that he won’t marry another woman unless she is with him ten consecutive years and she didn’t have any zera shel kayama.

User176: In your Sephardic community men who didn’t have children for 10 years marry a second wife?
In some communities it is customary to put in that tenai. It means if that would CS happen it would theoretically be acceptable to marry another wife that isn’t actually practiced in today’s day and age.
