cmd/devp2p: fix comparison of TXT record value (#22572)
* cmd/devp2p: fix comparison of TXT record value

The AWS API returns quoted DNS strings, so we must encode the new value
before comparing it against the existing record content.

* cmd/devp2p: add test

* cmd/devp2p: fix typo and rename val -> newValue

cmd/devp2p: fix error in updating the cursor when collecting records for route53 (#22538)
This PR fixes a regression introduced in #22360, when we updated to the v2 of the AWS sdk, which causes current crawler to just get the same first 100 results over and over, and get stuck in a loop.

cmd/devp2p: use AWS-SDK v2 (#22360)
This updates the DNS deployer to use AWS SDK v2. Migration is relatively
seamless, although there were two locations that required a slightly
different approach to achieve the same results. In particular, waiting for
DNS change propagation is very different with SDK v2. 

This change also optimizes DNS updates by publishing all changes before
waiting for propagation.

cmd/devp2p: be very correct about route53 change splitting (#20820)
Turns out the way RDATA limits work is documented after all,
I just didn't search right. The trick to make it work is to
count UPSERTs twice.

This also adds an additional check to ensure TTL changes are
applied on existing records.

cmd/devp2p: fix Route53 TXT record splitting (#20626)
For longer records and subtree entries, the deployer created two
separate TXT records. This doesn't work as intended because the client
will receive the two records in arbitrary order. The fix is to encode
longer values as "string1""string2" instead of "string1", "string2".
This encoding creates a single record on AWS Route53.

cmd/devp2p: submit Route53 changes in batches (#20524)
This change works around the 32k RDATA character limit per change
request and fixes several issues in the deployer which prevented it from
working for our production trees.
