[FIX] web: list view: don't rerender a row before the previous render is done

Setup:

  - Add a checkbox to the sublist view of quotations with studio and save
  - In the chrome devtools, select a custom network throttling profile
    with 1s of latency

Steps to reproduce:

  First example:

  - Go to a quotation with at least two lines
  - Enter edit mode
  - Change the quantity of the first line
  - Double click on the price field of the second line
  -> A traceback appears: `Cannot set properties of null (setting 'props')`

  Second example:
  - Go to a quotation with at least two lines
  - Enter edit mode
  - Change the quantity of the first line
  - Click on the price field of the second line
  - Click on Save
  -> The same traceback is there

Cause of the issue:

  The checkbox field is implemented in owl and thus the
  owl_compatibility layer is used.
  Mounted is not called on the checkbox if a new rendering is being done
  cf: https://github.com/odoo/odoo/pull/75950


  Currently, it is possible to set a row mode before the previous call
  and rendering is done.

Solution:

  Use a mutex for each record to prevent simultaneous render
