Optimizations plus bug fix

[NobodyXu]

• Optimize Download::and_extract: Avoid dup monomorphization
• Increase buffer size for binstall_crates_v1 to 4096 * 5
• Optimize opts::resolve: Avoid unnecessary clones
• Fix reserve in opts::resolve: Do not over-reserve
• Rename field opts::Options::resolver => resolvers
• Refactor: Extract new type resolve::PackageInfo
  • which makes opts::resolve_inner easier to understand
  • reduce number of parameters required for download_extract_and_verify and
    collect_bin_files
  • reducing size of future returned by opts::resolve_inner by dropping
    cargo_toml::{Manifest, Package} as early as possible since
    Manifest is 3000 Bytes large while Package is 600 Bytes large.
• Optimize fetchers::Data: Use CompactString for field name & version
  since they are usually small enough to fit in inlined version of
  CompactString.
• Optimize gh_crate_meta: Avoid unnecessary allocation
  in RepositoryHost::get_default_pkg_url_template.
• Refacator: Use Itertools::cartesian_product in apply_filenames_to_paths
• Optimize ops::resolve: Avoid unnecessary clone & reduce future size
  by calling fetcher.target_meta() to obtain final metadata after
  downloaded and extracted the binaries.
• Optimize ops::resolve: Avoid unnecessary allocation
  in download_extract_and_verify: Replace Itertools::join with
  Itertools::format to avoid allocating the string.
• Fix disabling cargo-install fallback
• Simplify BinFile::from_product: Takes &str instead of &Product
  since we only need product.name
• Rename BinFile::from_product => BinFile::new
• Refactor: Create newtype ops::resolve::Bin
  so that we don't need to unwrap() on Product::name
  and reduce memory usage.
