Currently, the magnification filter information is ignored
by SwiftShader. In order to fix it, the 1st step is simply
to make the sampler aware of this information. After this,
a subsequent cl using the duvdxy computed in computeLod
will choose which filter to use (if they are different).

Format validations were failing if the exact same format
wasn't used between different texture related calls to the
same texture, even when the formats were equivalent, so I
added a GetSizedInternalFormat function based on a format
map (courtesy of Angle). The validation checks were also
unified in utilities.cpp and used wherever texture formats
were used, to make sure Image objects used in Texture
objects always use the sized format, so that format
comparisons work properly.

- GL_OES_depth24
- GL_OES_depth32
- GL_EXT_color_buffer_half_float

These were mostly supported already with the GLES3 related changes,
so only a few minor changes were required.

- Implemented mipmap generation and completeness checks for
  Texture2DArray.
- Fixed texture parameters setters and getters along with
  mipmap generation functions to use the proper 2D array
  texture instead of the 3D texture for 2D array textures.
- Enabled the same path as 3D texture for 2D array textures
  in the sampler.
- Added an address function for the w component, which
  simply clamps the rounded value for 2D array textures and
  adapted SamplerCore::computeIndices to this new behavior.

BindRenderbuffer doesn't require anything except a non-zero
renderbuffer to create a new Renderbuffer object (it is not
required to use GenRenderbuffers before using BindRenderbuffer).
This had been fixed for GLES 3.0, but the same also applies
to GLES 2.0, which has been fixed here. Note that the Context
already handles the case where renderbuffer is zero properly.

  it must be a valid object.
- In FramebufferTexture2D, I moved the isCompressed check AFTER
  the textarget validation, to avoid using an invalid textarget.
- In GetFramebufferAttachmentParameteriv, not using GL_BACK,
  GL_DEPTH or GL_STENCIL for the default framebuffer should
  produce GL_INVALID_ENUM instead of GL_INVALID_OPERATION.
- In GetFramebufferAttachmentParameteriv, when
  attachmentObjectType is GL_NONE, in ES3, the query for
  GL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME should return 0.
