Switched to ACM TOMS template + stylistic adjustements

[vincent-maillou]

This PR:

• Switch the template to ACM TOMS
• Generated with AI (!) \city for each author, this need to be checked.
• Removed or commented out unnecessary packages or conflicting ones with acmart
• Unify the style of the listings (fontsize, background color)
• Put captions above table and listings (https://www.acm.org/publications/taps/latex-best-practices)
• Made tables full widths
• Introduce a new "compressed Listing" and a "Summary Table" (Ai generated!) for SpMV API comparisons [...]". The compressed listing is essentially the same as the initial one but under a single listing env for acmart it might be better, also take less space. The compressed table is a proposition that might be convenient for the reader to get at a glance the differences between APIs.

I also noticed that the way that the Pre-condition and Post-condition are written with the \\ can lead to weird placements with figures, listings and table (I had a post-condition alone one page further cut by a figure). This might need attention when finalizing the formatting of the document.

\begin{enumerate}
    \item \texttt{inspect phase} -- (optional) prepare any potential optimizations for subsequent phases (e.g.  internal transpose copies as applicable), or may do nothing
    \item \texttt{compute symbolic} -- computing the size of the sparse output structure, which typically requires significant work\\
    \textit{Post-Condition: The size of the sparse output structure is known.}
    \item \texttt{allocation phase} -- allocating the memory for the sparse output data structure and placing it in the output matrix object to be filled.
    \\
    \textit{Pre-Condition: The size of the sparse output structure is known.}\\
    \textit{Post-Condition: Sparse output structure is allocated.}
    \item \texttt{fill symbolic} -- filling the sparsity pattern into the output data structure
    \textit{Pre-Condition: Sparse output structure is allocated.}\\
    \textit{Post-Condition: Sparsity pattern in sparse output structure is filled and valid.}
    \item \texttt{compute numeric} -- complete the numerical computations and fill the result in the output data structure.\\
    \textit{Pre-Condition: Sparsity pattern in the sparse output structure is filled and valid.\\
    Post-Condition: Numeric values in the sparse output structure are filled and valid.}
