This PR moves the processing of options passed to the CLI from
`shell.cpp` to `Shell.lean`.
As with previous ports, this attempts to mirror as much of the original
behavior as possible, Benefits to be gained from the ported code can
come in later PRs. There should be no significant behavioral changes
from this port. Nonetheless, error reporting has changed some, hopefully
for the better. For instance, errors for improper argument
configurations has been made more consistent (e.g., Lean will now error
if numeric arguments fall outside the expected range for an option).
(Redo of #11345 to fix Windows issue.)

This PR translates `lean::mk_projections` into Lean, adding
`Lean.Meta.mkProjections`. It also puts `hasLooseBVarInExplicitDomain`
back in sync with the kernel version. Deletes
`src/library/constructions/projection.{h,cpp}`.
This PR introduces the central parallelism API for ensuring that helper
declarations can be generated lazily without duplicating work or
creating conflicts across threads.
This PR splits the environment used by the kernel from that used by the
elaborator, providing the foundation for tracking of asynchronously
elaborated declarations, which will exist as a concept only in the
latter.
Minor changes:
* kernel diagnostics are moved from an environment extension to a direct
environment as they are the only extension used directly by the kernel
* `initQuot` is moved from an environment header field to a direct
environment as it is the only header field used by the kernel; this also
makes the remaining header immutable after import
