[Feature] 转置表格（transpose = true），frozenRowCount无效，期望frozenRowCount也适用转置表格

[banshow]

What problem does this feature solve?

期望frozenRowCount这个配置属性跟bottomFrozenRowCount一样，也适用转置表格，即可冻结转置表格前几行。而目前frozenRowCount对转置表格无效

What does the proposed API look like?

const option = { transpose:true, frozenRowCount: 2 }
