Support template variables in command menu item labels (#18707)

- Adds template variable interpolation (`${...}`) to command menu item
labels and short labels, enabling dynamic text like `Create new
${capitalize(objectMetadataItem.labelSingular)}` instead of static
`Create new record`.
- Supports `capitalize` and `lowercase` transform functions within
template expressions.
