Anton Bikineev 3eefe03c51 cppgc: Add simple check/dcheck facilities
A few notes:
1) Oilpan is a generic library, meaning that it can work with arbitrary
user types. The library is split in type-aware (include/) and
type-erased (src/) parts. The former comprises a lot of code that still
needs to be defended with dchecks;
2) Macros are prefixed with CPPGC_, so that they don't clash in the user
code with similar macros from other libraries;
3) The macros simply forward requests to V8 so that dcheck handlers can
be configured uniformly;
4) The CL doesn't contain CHECK_EQ and friends, but they can be added
later if needed.
