refactor: remove "ext/flash" (#18578)

With https://github.com/denoland/deno/pull/18568 landed we no longer
need "ext/flash". 

This commit removes "deno_flash" extension completely.

This should have some impact on the binary and snapshot size.

Closes https://github.com/denoland/deno/issues/17356
