Returns true if the font table idetified by tag exists in the font; returns false otherwise.

If buffer is \nullptr, stores the size of the buffer required for the font table data, in bytes, in length. If buffer is not \nullptr and the capacity of the buffer, passed in length, is sufficient to store the font table data, also copies the font table data to buffer.

Note: returning false when the font table exists could lead to an undefined behavior.
