8a54576861 Use std::vector instead of boost::container::small_vector under MSan 
There are some issues with dtors in boost::container::small_vector
and/or vector, which is reported by MSan as an error.

The suppression __attribute__((no_sanitize_memory)) works until
clang-15, but since clang-16 it does not. It looks like before clang-16
this no_sanitize_memory works for all child functions, while since
clang-16 only for this function. I've tried to add few others, but a) it
looks icky b) I haven't managed to finish this process.

Also I've measured the performance and it hadn't been changed. Though
boost::small_vector should be faster then std::vector, but apparently my
particular case hadn't affected too much.

And one more thing, MSan reports this only with -O0, with -O3 - it is
not reproduced.

<details>

_Note: it was slightly trimmed_

2731a3384b Fix segfaults on allocation failure (#4) 
Throw std::bad_alloc instead of returning nullptr from
ue2::AlignedAllocator. Allocators for STL containers are expected never
to return with an invalid pointer, and instead must throw on failure.
Violating this expectation can lead to invalid pointer dereferences.
