  [libc][CPP] Add vector container and unit tests (#222972)

Sequential group database entrypoints require dynamically resizable
buffers to parse arbitrary-length records and member lists reliably.
Rather than managing raw heap reallocations manually within subsystem
parsers, dynamic growth is encapsulated in a dedicated cpp::vector
container.

Add cpp::vector in libc/src/__support/CPP/vector.h with move semantics,
safe fallible allocation (returning bool for out-of-memory handling
without C++ exceptions), and RAII clean-up for trivially and
non-trivially destructible types.

* Add vector header library in libc/src/__support/CPP/CMakeLists.txt
* Implement vector container in libc/src/__support/CPP/vector.h
* Add comprehensive unit tests in
libc/test/src/__support/CPP/vector_test.cpp
* Register vector_test in libc/test/src/__support/CPP/CMakeLists.txt

Assisted-by: Automated tooling, human reviewed.
