Erik Grinaker f755979102 pageserver: payload compression for gRPC base backups (#12346) ...

## Problem

gRPC base backups use gRPC compression. However, this has two problems:

* Base backup caching will cache compressed base backups (making gRPC
compression pointless).
* Tonic does not support varying the compression level, and zstd default
level is 10% slower than gzip fastest level.

## Summary of changes

This patch adds a gRPC parameter `BaseBackupRequest::compression`
specifying the compression algorithm. It also moves compression into
`send_basebackup_tarball` to reduce code duplication.

A follow-up PR will integrate the base backup cache with gRPC.
