- [GPU] Rename TextureMemoryUsage to TextureExtent (and relevant functions/etc).

- [GPU] Precalculate memory byte usage for base mip (and any additional mip levels).
- [GPU] Change TextureCache::WatchCallback so that if it's fired multiple times for the same texture it does not assert.
- [GPU] Add write watches for texture memory associated with additional mipmap levels.
