Subject: [IMP] web: many2many_binary, binary, image, add the option
 ``accepted_file_extensions``

Purpose
=======
We want to add an option on the widgets
- many2many_binary,
- binary,
- image

This option specifies what file extensions the user can pick from the file input dialog box.

Examples
========
```xml
<field widget="many2many_binary" options="{'accepted_file_extensions': 'image/*'}"/>
<field widget="many2many_binary" options="{'accepted_file_extensions': '.png,.jpeg'}"/>
<field widget="many2many_binary" options="{'accepted_file_extensions': 'application/pdf'}"/>
<field widget="image" options="{'accepted_file_extensions': '.png,.jpeg'}"/>
<field widget="binary" options="{'accepted_file_extensions': '.pdf,.svg'}"/>
```

How
===
Add an option (accepted_file_extensions) in the template ``HiddenInputFile`` (the widget many2many_binary is using this template)
So, we can also use this new option in others widgets using ``HiddenInputFile``
In the many2many_binary, read the ``nodeOptions`` and set the widget attribute ``accepted_file_extensions``

We also have to fix some other widget, because an property ``image_only`` was already existing in the template ``HiddenInputFile``
(we just need to replace ``image_only=True`` to ``accepted_file_extensions='image/*'``

The widget ``FieldPdfViewer`` (pdf_viewer) now use the new option to filtrate PDF
(instead of removing the <input/> and adding <input accept='.pdf'/>).

Tests
=====
We also test if the option is correctly set on the <input/>
- binary
- image
- many2many_binary

Impacted widgets
===============
- many2many_binary
- image: this widget use ``options="{accepted_file_extensions='image/*'}"`` instead of ``image_only=True``
- tablet_image: same as ``image``
