d0601c0a83 TextureConversionShader: Use round() instead of roundEven() in HLSL 
HLSL does not define roundEven(), only round(). This means that the
output may differ slightly for OpenGL vs Direct3D. However, it ensures
consistency across OpenGL drivers, as round() in GLSL can go either way.

1b32751367 VideoCommon: Round values in swizzlers. 
This was breaking Metroid Prime 2: Echoes’s scanner in some rooms, such
as the one in https://fifoci.dolphin-emu.org/dff/mp2-scanner/

It was found on Ivy Bridge on Mesa, the alpha value read back from the
EFB was off-by-4 in multiple objects, which was a conversion error
because int4() is equivalent to floor() and the value wasn’t always
higher.

c3a57bbad5 Video: Clearly separate Texture and EFB Copy formats 
Improve bookkeeping around formats. Hopefully make code less confusing.

- Rename TlutFormat -> TLUTFormat to follow conventions.
- Use enum classes to prevent using a Texture format where an EFB Copy format
  is expected or vice-versa.
- Use common EFBCopyFormat names regardless of depth and YUV configurations.

05b4d14bf0 TextureConversionShader: fix syntax error 
Fixes a situation where the following invalid GLSL code is generated:

```glsl
float3 texSample0 = texture(samp0, float3(uv0 + float2(0, 0) * sample_offset, 0.0)).rgb;
float3 texSample0 = floor(float3 texSample0 * 63.0) / 63.0;
float3 texSample1 = texture(samp0, float3(uv0 + float2(1, 0) * sample_offset, 0.0)).rgb;
float3 texSample1 = floor(float3 texSample1 * 63.0) / 63.0;
```

3847e226ab TextureConversionShader: Consider source format of EFB for EFB2RAM 
Currently, we use the alpha channel from the EFB even if the current
format does not include an alpha channel. Now, the alpha channel is set
to 1 if the format does not have an alpha channel, as well as truncating
to 5/6 bits per channel. This matches the EFB-to-texture behavior.

b9be3245e1 Move common EFB copy code into VideoCommon 
Addded a few duplicated depth copy texture formats to the enum

in TextureCacheBase and the ogl/dx11 texture cache implementations.

57d94de2ad Fix regression for D3D EFB depth copies. 
On D3D, we read from the depth buffer using the format
DXGI_FORMAT_R24_UNORM_X8_TYPELESS (essentially, the "r" component contains
the depth, and the other components contain nothing).

b0b99b6922 Fix shader so it's possible to use with D3D Map(). 
Well, that's not strictly true, but trying to memcpy between two buffers
using different row lengths and different strides is at minimum extremely
unintuitive.

bc9ef95643 Support Sampler binding in the shader. 
In the cases where we support the binding layout keyword, use it for more than binding UBO location.
This changes it so it is supported for samplers as well.

Instances when this is enabled is if a device supports GL_ARB_shading_language_420pack, or if it supports GLES 3.10.
