Subject: [PATCH] intervals: pass precision to `BigFloat` instead of changing
 globally

Taking the lock is still necessary after this change. It'd be necessary
to audit all `BigFloat` methods to prove otherwise. Also see
https://github.com/JuliaLang/julia/pull/49749, which fixes some of them
in Julia `Base`.
