Make EphemeralFile::write_blob function async (#5056)

Browse Source 
## Problem

The `EphemeralFile::write_blob` function accesses the page cache
internally. We want to require `async` for these accesses in #5023.

## Summary of changes

This removes the implementaiton of the `BlobWriter` trait for
`EphemeralFile` and turns the `write_blob` function into an inherent
function. We can then make it async as well as the `push_bytes`
function. We move the `SER_BUFFER` thread-local into the
`InMemoryLayerInner` so that the same buffer can be accessed by
different threads as the async is (potentially) moved between threads.

Part of #4743, preparation for #5023.
