rust: alloc: add `Vec::try_with_capacity{,_in}()` constructors
Add `Vec::try_with_capacity()` and `Vec::try_with_capacity_in()` as
the fallible versions of `Vec::with_capacity()` and
`Vec::with_capacity_in()`, respectively.
The implementations follow the originals and use the previously
added `RawVec::try_with_capacity_in()`.
In turn, `Vec::try_with_capacity()` will be used to implement
the `CString` type (which wraps a `Vec<u8>`) in a later patch.
