feat(render-engine): move cache to viewport

[lumixraku]

A description of the proposed changes:
Moving the cache canvas from the spreadsheet to the viewport is primarily for the scenario of freezing rows and columns.

How to test them:

• Performance: The FPS performance during scrolling should theoretically be consistent with the performance when there are no frozen rows or columns.

• Font rendering: specially in scenarios involving overflow and merged cells spanning frozen rows and columns.

• Correct texture mapping: such as avoiding blank textures and ensuring complete rendering of text and background colors.

BREAKING CHANGE:
Before:
cache canvas was controlled by spreadsheet.
After:
cache canvas was created by viewport
