Make CVC/API BV div/mod semantics match SMT-LIB (#4997)
This commit changes the semantics of the CVC language and with the
default semantics of the API for `BVUDIV`, `BVUREM`, `BVSDIV`, `BVSREM`,
and `BVSMOD` to match the semantics of SMT-LIB >=2.6. Relatedly, the
commit also adds comments to our API documentation for the different
semantics enabled by the `bv-div-zero-const` option.
