Subject: [PATCH 2/6] WIP: cirrus/windows: ccache

ccache v4.10 supports PCH, so this now seems viable.
(ccache 4.7 added support for depend mode with MSVC).

https://www.postgresql.org/message-id/flat/20220522232606.GZ19626%40telsasoft.com

ccache should be installed in the VM rather than with choco in each
invocation.
