Vulkan: Enable 16-bit norm support for tex buffers According to the spec for EXT_texture_norm16, it enables texture buffers to support the following additional formats: * GL_R16_EXT * GL_RG16_EXT * GL_RGBA16_EXT All of the above are unsigned short normalized values. * Updated validation to support the aforementioned formats in texture buffers in case of support for the norm16 extension. * Updated AdjustViewFormatForSampler() to also support norm16 values. * Added the condition for advertising textureNorm16EXT that the 16-bit UNORM formats above should have the buffer feature bit for texture buffer support: VK_FORMAT_FEATURE_UNIFORM_TEXEL_BUFFER_BIT * Added support check for renderSnormEXT after textureNorm16EXT, since the check for former currently uses the support for latter as a parameter. * Added unit tests to draw using a texture buffer with norm16 formats. * Added TextureBufferTestBase in order to test the API calls in the extensions and the core ES 3.2 version, which the following suites are derived from: * TextureBufferTestES31 (existing) * TextureBufferTestES32 (new) * Extended the tests to similar 8-bit formats.
