Adding type signatures to `#audit_formula` methods in formula cops
would lead to verbose, repetitive signatures across the existing ~63
instances. This reworks `#audit_formula` to use a `T::Struct` for its
arguments, which allows us to use a one-line signature for these
methods.
- Only two audits were using this: `audit_keg_only_reason` and `audit_text`,
and they weren't using any of its text processing methods, so there's little
reason to keep it around.
- The "`keg_only_reason` shouldn't contain 'HOMEBREW_PREFIX'" audit can easily
be replaced with a RuboCop since that's "just" text parsing.
- The "tests should invoke binaries with `bin/<command>`" audit had to stay as
a FormulaAudit because it requires accessing attributes about the Formula
like its name, aliases, which RuboCop can't get to, but it was easy to move the
singular "read the text in the file" line from `FormulaTextAuditor`.
This currently no longer applies, because we might sometimes need an
older `setuptools` than the one shipped with a Python formula.
This is needed for Homebrew/homebrew-core#93964.
When building Rust packages that provide libraries but no executable
binaries, `cargo install` doesn't do anything; you need to use `cargo
build` and install any libraries manually. See e.g.
rust-lang/cargo#8294.
Unfortunately, Homebrew's Rubocop "use cargo install *std_cargo_args"
rule, as currently written, blocks all invocations of `cargo build`.
This commit changes that rule to exclude invocations of `cargo build`
that use the `--lib` argument (`--lib` specifies to Cargo that a
package's library targets should be built). This will enable library
packages to be built while retaining the "use cargo install
*std_cargo_args" message for the more common case when a Rust package
provides executable binaries.

https://developer.apple.com/documentation/accelerate
- Veclibfort exists only to wrap Accelerate's BLAS/LAPACK
- LAPACK is a slow, seldom updated reference implementation
- Encourage usage of OpenBLAS
