roachtest: provision 250 MB/s for restore tests on AWS

The restore/tpce/* family of tests on AWS max out the default 125 MB/s EBS
throughput. In contrast, similar tests in GCE provision for more throughput and
don't max it out.

This commit bumps the provisioned throughput from 125 MB/s to 250 MB/s in all
restore tests on AWS, so that the tests don't work at the edge of overload.

This both brings some parity between testing on GCE and AWS, and reduces
likelyhood of raft OOMs (which manifest more often when disk is overloaded).

Fixes #106248
Epic: none
Release note: none
