    mesa: Don't use memcpy() in _mesa_texstore() for float depth texture data

    because float depth texture data needs clamping to [0.0, 1.0]. Let the
    _mesa_texstore() fallback to slower path.

    Fixes Khronos GLES3 CTS tests:

    V2: Move the check to _mesa_texstore_can_use_memcpy() function.
        Add check for floating point data types.
