3 cdr quints cost about the same as a 6300 ip champion

Shyvana's W lasts up to 7 seconds if you auto 4 times and 40% CDR will make the W cd only 7.2 seconds. Shyvana's E lasts 5 seconds and has a 4.8 second CD with 40% CDR. Her Q has a 3 second CD at 40% CDR and goes down by .5 seconds with every auto.

You've got it backwards mate. Shyvana's CD's all scaling with auto attacks doesn't make CDR less valuable on her, it makes it more valuable, and exponentially so. A Shyvana with no CDR has a CD of 12 seconds on her W and it lasts up to 7 seconds, meaning she has a minimum of 5 seconds of downtime on her W if she has no CDR. A Shyvana with 40% CDR has a CD of 7.2 seconds on her W and it still lasts up to 7 seconds, leaving an effective downtime of .2 seconds. Going from 5 seconds of downtime to .2 seconds is an effective 96% CD reduction on your most important ability. CDR isn't less valuable on Shyv, it's more valuable.

But she still doesn't need it. Also, it is very difficult to itemize for cooldown reduction on Shyvana, since most cooldown reduction items have wasted stats for her. Most 20% CDR items have wasted stats: Frozen Heart has wasted mana, Nashor's Tooth has wasted AP, and I don't even need to talk about Morellonomicon/Athene's Unholy Grail. The Black Cleaver actually has non-wasted stats for Shyvana, but she doesn't benefit very much from armor penetration when more than half of her damage is magic, and this item lacks attack speed which is important for Shyvana.

She runs into similar problems for 10% CDR items. Spirit Visage is a good item, but Shyvana lacks natural sustain so she is not going to take full advantage of the passive. Also, this item is useless against full AD teams. Zephyr is not a bad item for Shyvana, but it offers no tankyness at all. Same for Youmuu's Ghostblade. Locket of the Iron Solari can be used and it's a fairly good item too, but Shyvana will generally like the extra magic resistance from Banshee's Veil more, since she is more of a selfish champion. If Iceborn Gauntlet didn't had too much gold wasted on mana, I am sure that it would be a fairly good item for Shyvana.

There is also Ionian Boots of Lucidity. But those boots offer no tankyness at all. Shyvana would rather use Ninja Tabi or Mercury's Treads.

You can use cooldown reduction runes, but then you are giving up stats for it. Cooldown reduction glyphs means that Shyvana cannot use magic resistance glyphs, and cooldown reduction quintessences means that Shyvana cannot use attack speed, attack damage, or even movement speed quintessences, all which are much better options.

I actually think that it's good that Shyvana doesn't rely on CDR, because Shyvana is an AD manaless champion without natural sustain that needs to build tanky, so it is fairly difficult for her to have good options for cooldown reduction.

She can still benefit from building CDR, but again, it is simply not a core stat for her. It's like itemizing for CDR on Yasuo. Why would you do that? His Q and his E are unnafected by cooldown reduction and his Q is even reduced by attack speed. His W and his ult benefit from CDR, but his W has a fairly long cooldown anyway, and his ult has a fairly low cooldown when compared to most ultimates.
