chore(blooms)!: Remove bloom compactor component (#13969)

**What this PR does / why we need it**:

This commit removes the code related to the bloom compactor which is superseded by the bloom planner and builders.

A handful of CLI arguments of per-tenant settings changed their prefix from `-bloom-compactor.*` to `-bloom-build.*`. Other settings for the compactor component itself, also prefixed with `-bloom-compactor.*` were removed. See upgrade docs for further information.

**Special notes for your reviewer**:

:heavy_check_mark: Part of #13957

📔 Documentation update #13965

⚠️ Integrating the bloom planner and builder into the `backend` target is done in a follow-up PR.

 The actual block size might exceed this limit given that we append streams blooms to the block until the 
 block is larger than the configured maximum size. Blocks are created in memory and as soon as they are written to the 
 object store they are freed. Chunks and TSDB files are downloaded from the object store to the file system.
