Yuchen Liang cacb1ae333 pageserver: set default io_buffer_alignment to 512 bytes (#8878) ...

## Summary of changes

- Setting default io_buffer_alignment to 512 bytes. 
- Fix places that assumed `DEFAULT_IO_BUFFER_ALIGNMENT=0`
- Adapt unit tests to handle merge with `chunk size <= 4096`.

## Testing and Performance

We have done sufficient performance de-risking. 

Enabling it by default completes our correctness de-risking before the
next release.
