Fixes some bugs with the log refactor (#3835). Namely, quiet mode
progress printing and missing string interpolation in the fetching cloud
release caption.
This is a major refactor of Lake's build code. The key changes:
* **Job Registration**: Significant build jobs are now registered by
build functions. The DSL inserts this registration automatically into
user-defined targets and facets, so this change should require no
end-user adaption. Registered jobs are incrementally awaited by the main
build function and the progress counter now indicates how many of these
jobs are completed and left-to-await. On the positive side, this means
the counter is now always accurate. On the negative side, this means
that jobs are displayed even if they are no-ops (i.e., if the target is
already up-to-date).
* **Log Retention**: Logs are now part of a Lake monad's state instead
of being eagerly printed. As a result, build jobs retain their logs.
Using this change, logs are are now always printed after their
associated caption (e.g., `[X/Y] Building Foo`) and are not arbitrarily
interleaved with the output of other jobs.
* **Simplify the build monad stack**: Previously, there was a lot of
confused mixing between the various build monads in the codebase (i.e.,
`JobM`, `ScedulerM`, `BuildM`, `RecBuildM`, and `IndexBuildM` ). This
refactor attempts to make there use more consistent and straightforward:
* `FetchM` (formerly `IndexBuildM`) is the top-level build monad used by
targets and facets and is now uniformly used in the codebase for all
top-level build functions.
* `JobM` is the monad of asynchronous build jobs. It is more limited
than `FetchM` due to the fact that the build cache can not be modified
asynchronously.
* `SpawnM` (formerly `SchedulerM`) is the monad used to spawn build
jobs. It lifts into `FetchM`.
* `RecBuildM` and `CoreBuildM` (formerly `BuildM`) have been relegated
to internal details of how `FetchM` / `JobM` are implemented / run and
are no longer used outside of that context.
* **Pretty progress.** Build progress (e.g., `[X/Y] Building Foo`) is
now updated on a single line via ANSI escape sequences when Lake is
outputting to a terminal. Redirected Lake output still sees progress on
separate lines.
* **Warnings-as-error option.** Adds a `--wfail` option to Lake that
will cause a build to fail if Lake logs any warnings doing a build.
Unlike some systems, this does not convert warnings into errors and it
does not abort jobs which log warnings. Instead, only the top-level
build fails.
* **Build log cache.** Logs from builds are now cached to a file and
replayed when the build is revisited. For example, this means multiple
runs of a `--wfail` Lean build (without changes) will still produce the
same warnings even though there is now an up-to-date `.olean` for the
module.
Closes#2349. Closes#2764.
Adds an alternative TOML configuration format to Lake.
* Uses TOML v1.0.0 and is fully specification compliant (tested via
[toml-test v1.4.0](https://github.com/toml-lang/toml-test/tree/v1.4.0)).
* Supports package configuration options, Lean libraries, Lean
executables, and dependencies.
* TOML configurations can be generated for new projects via `lake
new|init <pkg> <template>.toml`.
* Supported configurations can be converted to/from TOML via `lake
translate-config <lang>`.
On Windows, we now compile all core `.o`s twice, once with and without
`dllexport`, for use in the shipped dynamic and static libraries,
respectively. On other platforms, we export always as before to avoid
the duplicate work.

Improves executable handling in `lake exe` and `lake init`:
* `lake exe <target>` now parses `target` like a build target (as the
help text states it should) rather than as a basic name.
* `lake new foo.bar [std]` now generates executables named `foo-bar`.
* `lake new foo.bar exe` now properly creates `foo/bar.lean`.
This PR adds per-package server options to resolve#2455. It is based on
the previous work in #2456, but takes a different approach: options are
loaded for the specific file in the file worker when `print-paths` is
called, instead of loading them in the watchdog with a separate Lake
command. This change addresses review comments made in #2456.
In doing so, it introduces two new Lake config fields:
- `leanOptions`: `-D` flag options that are passed to both the language
server and `lean` when building.
- `moreServerOptions`: `-D` flag options that are passed to the language
server.
Since `print-paths` must also accept a file path to compute the options
for that file, this PR is changing the API for `print-paths`. As there
have been numerous complaints about the name `print-paths`, I also
decided to change it to `setup-file` in this PR, since it would break
compatibility with the old Lake API anyways.
This PR deprecates the Lakefile field `moreServerArgs` in favor of
`moreGlobalServerArgs`, as suggested in the review for #2456.
Fixes#2455
