mdbx: release v0.11.12 (Эребуни)

The stable bugfix release.

Fixes:
------

 - Fixed static assertion failure on platforms where the `off_t` type is wider
   than corresponding fields of `struct flock` used for file locking (backport).
   Now _libmdbx_ will use `fcntl64(F_GETLK64/F_SETLK64/F_SETLKW64)` if available.
 - Fixed assertion check inside `page_retire_ex()` (backport).

Minors:
-------

 - Fixed `-Wint-to-pointer-cast` warnings while casting to `mdbx_tid_t` (backport).
 - Removed needless `LockFileEx()` inside `mdbx_env_copy()` (backport).
