    GH-53615: [C++][Parquet] Add ALP to file-level fuzz corpus (#53671)
    
    ### Rationale for this change
    
    Follow up on #48345 by including ALP in the generated Parquet file-level 
fuzz corpus.
    
    ### What changes are included in this PR?
    
    Add `Encoding::ALP` to `kFloatEncodings`.
    
    ### Are these changes tested?
    
    N/A.
    
    ### Are there any user-facing changes?
    
    No. This only changes fuzzing seed generation, not production reader or 
writer behavior.
    
    ### Was AI used for this PR?
