[EuiInlineEditText] Option to not truncate text

**Problem Statement**

EuiInlineEditText always truncates text. There are cases where users want editable text, but do not want it to be truncated.

**Proposed Solution**

A potential solution is to provide a prop like `truncate=false`.

**Use Case**

Observability Solution > Management UX. Wanted to use this in the "description" field of an EuiPageHeader.

Requested by @kdelemme.

**Value / Impact**

It's not widely useful. This component is not used a lot and there's only one known location where this is needed, at this time.

**Urgency**

This is not urgent, there is a workaround for now with custom CSS overrides.

**Do alternatives or workarounds exist?**

This is the current workaround we've put together. It's a lot of overriding and likely prone to break if we tweak the styles in EuiEmptyButton in the future.
