sci-libs/brial: new library for polynomials over boolean rings.

This library is maintained upstream and in the sage-on-gentoo overlay
by François Bissey, but it is well-packaged and passes its tests. It
is a dependency of SageMath, and the system copy will eventually be
usable by Sage, so now is a good time to adopt it. The overlay ebuild
was used with minimal changes.

Closes: https://bugs.gentoo.org/713330
Package-Manager: Portage-2.3.89, Repoman-2.3.20

+    BRiAl is a C++ library (the successor to PolyBoRi) that provides
+    high-level data types for Boolean polynomials and monomials,
+    exponent vectors, as well as for the underlying polynomial rings
+    and subsets of the powerset of the Boolean variables.
