bug#61849: 29.0.60; Unable to use treesit-install-language-grammar because repo doesn't have parser.c

[Misha Zharov]

Add (sql "https://github.com/m-novikov/tree-sitter-sql";) to
treesit-language-source-alist. Then use
treesit-install-language-grammar. The following error occurs:

    Error encountered when installing language grammar: (treesit-error
    Command: cc -fPIC -c -I. parser.c Error output: cc1: fatal error:
    parser.c: No such file or directory compilation terminated.)

This error occurs because we need to run a configuration step on the
repo to generate parser.c. I believe this is because we need to either
run `npm run generate` or `tree-sitter generate` to generate the
`src/parser.c` file. It would be nice if we could implement a patch to:

  1. Allow users to specify a configuration step to configure the repo
     before searching for parser.c (like passing a lambda into
     `treesit-language-source-alist`)
  2. Allow users to specify a git hash that should be checked out before
     the configuration step is run. I know currently different branches
     are supported, but not all projects have release branches.
  3. Alternatively this function can be split into 2 function, the first one
      would clone and configure the repository, and well as find the
      required files. The second function would simply compile the required
      files into the shared libraries, and move them to the appropriate location

I can have a go at implementing some of the above if those changes are
welcome. The reason this is important is because it seems like more
repos in the future will move away from providing the autogenerated
files in their repos, so this function might be on borrowed time in its
current incarnation.
