Subject: [IMP] web: add control + create tags to customize "add a line"

The default "add a line" button creates a new line with the default values from the model. Sometimes we want to create a new line with different default values (or more generally a customized context), which is possible with this commit. Moreover it is possible to create multiple buttons for multiple default values/contexts.

This works both for in-line creation ("editable=") and dialog creation.

The new tags are:

<control> defines custom controls for the current view.

Does not support any attribute, but can have children:

<create> adds a button to create a new element on the current list.

This makes sense when the parent tree view is inside a One2many field.

If any create is defined, it will overwrite the default "add a line" button.

For more information and example, have a look at the Views documentation.

Technically, the commit will:
- parse the new XML tags (+ add appropriate validation)
- display the buttons based on the XML
- on button click/keyboard: pull up the additional context information from the button event up to the default_get
- add unit tests
- add documentation

PR #25209
