GameINI: Shadow the Hedgehog texture cache default

Adjusts the Texture Cache settings/slider to 512 samples which equates
to the 'middle' option in the UI.

If using the 'Safe' Texture Cache Accuracy mode, the left screen will only render bloom in 2P modes.
If using the 'Fast' Texture Cache Accuracy mode, the Intro Movie will
drop frames near the end when the "Shadow the Hedgehog" game title
letters appear. This mode also can result in artifacts/bleed from bloom
effects in some situations.
