Adds an editable text label to the gr-change-metadata for modifying the topic of a change. Introduces the gr-editable-label as a UI element for editable text labels. Editing the topic is only allowed if the user is logged in and has the topic-edit permission. This is a redo of change 78110, which had been rebased wrong and had to be reverted. https://gerrit-review.googlesource.com/c/78110/ Bug: Issue 4102 Change-Id: Ia7bb7b803a9fdd15a5f9f0f8eecf77bdd3ee4ba7
