This commit refactors the current model structure of spreadsheet-related
module. Data fields are integrated into an abstract model
`spreadsheet.mixin` and all sub-models are inherited from it. This way
we can group all decode/encode logics into one place.

The spreadsheet module is moved to the community version
for the upcoming spreadsheet dashboards
This module is the core engine of spreadsheets in Odoo.
It contains `o-spreadsheet` library (o_spreadsheet.js) and all basic
integrations with odoo such as accounting formulas, lists, pivot, filters, etc.
This module alone does not have any action or menu to open a spreadsheet.
Those actions come with `documents_spreadsheet` module or the upcoming
`spreadsheet_dashboard` module.
