Erik Grinaker 9e55d79803 Reapply "pageserver: revert flush backpressure" (#10270) (#10402) ...

This reapplies #10135. Just removing this flush backpressure without
further mitigations caused read amp increases during bulk ingestion
(predictably), so it was reverted. We will replace it by
compaction-based backpressure.

## Problem

In #8550, we made the flush loop wait for uploads after every layer.
This was to avoid unbounded buildup of uploads, and to reduce compaction
debt. However, the approach has several problems:

* It prevents upload parallelism.
* It prevents flush and upload pipelining.
* It slows down ingestion even when there is no need to backpressure.
* It does not directly backpressure based on compaction debt and read
amplification.

We will instead implement compaction-based backpressure in a PR
immediately following this removal (#5415).

Touches #5415.
Touches #10095.

## Summary of changes

Remove waiting on the upload queue in the flush loop.
