[FIX] web, *: review Bootstrap tooltip/popover sanitization

* website_sale_comparison

The Bootstrap sanitization introduced with BS 4.3.1 was disabled with

https://github.com/odoo/odoo/commit/ee94decd30c4514d5bc410b1652bc6464bb600aa



This commit re-enables it by default but extends it to accept more
common tag names like tables and buttons. If a specific tooltip or
popover must accept custom tags or attributes (such as data-* attributes
required by a related JS), they must be supplied through the whitelist
BS parameter explicitely (see example with website_sale_comparison in
this commit).

Note: data-oe-* attributes are also whiteListed by default.

We cannot disable sanitization because bootstrap uses tooltip/popover
DOM attributes in an "unsafe" way.
