Allow to transfer all Thread datasets with TLV (#22183)

* Allow to transfer all Thread datasets with TLV

This commit allows to transfer all Thread datasets with TLV. Since
PR #22022 the preferred dataset is transmitted when using Matter
external commissioning. This commit makes the Thread configuration
dialog to have feature parity.

* Drop preferred border agent id as additional metric for default router

We always have the extended address, so use this as primary and only
metric which router is the default. The preferred border agent id gets
updated best effort.

Also use isDefaultRouter consistently in the code.
