Description / Motivation

Today we only have ASSERT_BSONOBJ_EQ (and related variants) for comparing BSONObj instances in tests. This causes the test to abort on first mismatch, which is inconvenient when:

• You want to check multiple BSON comparisons in a single test and see all mismatches.

• You’re converting ASSERT-based tests to EXPECT-based style for consistency with other gtest-style expectations.

A non-fatal EXPECT_BSONOBJ_EQ helper would be nice.
