feat: embed and check githash in .olean (#2766) 
This is an additional safety net on top of #2749: it protects users that
circumvent the build system (e.g. with `lake env`) as well as obviates
the need for TOCTOU-like race condition checks in the build system.

The check is activated by `CHECK_OLEAN_VERSION=ON`, which now defaults
to `OFF` as the sensible default for local development. When activated,
`USE_GITHASH=ON` is also force-enabled for stage 0 in order to make sure
that stage 1 can load its own core library.
