Convert MaxTextureCacheCapacity to Dynamic MaxTextureCacheCapacity for High Resolution Mod support. (#7307)

* Add Texture Size Capacity and 8GB Dram Build

* Update AutoDeleteCache.cs

* Dynamic Texture Cache (WIP)

* Change to float Multiplier, in-case it needs fine-tuning.

* Delete src/src.sln

* Update AutoDeleteCache.cs

* Format

* Fix Formatting

* Add DefaultTextureSizeCapacity and MemoryScaleFactor

- Also remove redundant New Lines

* Fix 4GB dram crashing

* Format newline

* Refractor

- Added Initialize() function to TextureCache and AutoDeleteCache
- Removed GetMaxTextureCapacity() function and instead added _maxCacheMemoryUsage
- Added private const MaxTextureSizeCapacity to AutoDelete Cache
- Added TextureCache.Initialize() to MemoryManager in order to fetch MaxGpuMemory at the right time.
- Moved and Changed Logger.Info for Gpu Memory to Logger.Notice and Moved it to PrintGpuInformation function.
- Opted to use a ternary operator for the Initialize function, I think it looks cleaner than bunch of if statements.

* Update src/Ryujinx.Graphics.Gpu/Image/AutoDeleteCache.cs

* maxMemory to CacheMemory, use Clamp instead of Ternary. Changed MinTextureCapacity 1GiB to 512 MiB

* Update src/Ryujinx.Graphics.Gpu/Image/AutoDeleteCache.cs

* Format comment

* comment context

* Increase TextureSize capacity for OpenGL back to 1024

- Added a new const ulong for OpenGLTextureSizeCapacity

* Fix changes from last commit.

* Adjust last OpenGL changes.

* Remove garbage VSC file

* Update src/Ryujinx.Graphics.Gpu/Image/AutoDeleteCache.cs
