Adjust powerwash requirements notification for FlexOrgs

Adjust IDS_POWERWASH_REQUEST_MESSAGE_FOR_ARC and
IDS_POWERWASH_REQUEST_MESSAGE_FOR_CROSTINI to support FlexOrgs by
adjusting the domain placeholder names and descriptions to make it
easier for the translators to understand the usage of the texts.

Additionally replace a call to
BrowserPolicyConnectorChromeOS::GetEnterpriseDisplayDomain with a call
to BrowserPolicyConnectorChromeOS::GetEnterpriseDomainManager.
