MDL-67668 behat: Add inplace editable field type

This commit promotes the Inplace Editable field to a first-class form
element by introducing a new partial selector for inplace editable
fields, and teaching the field manager how to recognise these, then
introducing a new field type which can handle setting values for this
field.

+Feature: Verify that the inplace editable field works as expected
+  In order to use behat step definitions
+  As a test write
+  I need to ensure that the inplace editable works in forms
+
+  Background:
+    Given the following "course" exists:
+      | fullname  | Course 1 |
+      | shortname | C1       |
+    And the following "activities" exist:
+      | activity | course | name                | idnumber |
+      | forum    | C1     | My first forum      | forum1   |
+      | assign   | C1     | My first assignment | assign1  |
+      | quiz     | C1     | My first quiz       | quiz1    |
+    And I log in as "admin"
+    And I am on "Course 1" course homepage with editing mode on
+
+  @javascript
+  Scenario: Using an inplace editable updates the name of an activity
+    When I set the field "Edit title" in the "My first assignment" "activity" to "Coursework submission"
+    Then I should see "Coursework submission"
+    And I should not see "My first assignment"
+    But I should see "My first forum"
+    And I should see "My first quiz"
+    And I set the field "Edit title" in the "Coursework submission" "activity" to "My first assignment"
+    And I should not see "Coursework submission"
+    But I should see "My first assignment"
+    And I should see "My first forum"
+    And I should see "My first quiz"
