Enable blending for 32FP formats

In order for SwANGLE to expose GL_EXT_float_blend,
R32F, RG32F and RGBA32F must all allow blending.
The code already supports this, we just need to
expose the VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BLEND_BIT
bit for these formats.

Tests: dEQP-VK.pipeline.blend.*32_sfloat*
