Migration from Boost to std c++ functionality

If the switch is delayed, it might become difficult to find any potential issue that might arise due to the switch., reducing confidence in the stability of the release.

Expected Behavior

static_assert(std::is_same_v<pcl::shared_ptr<int>, std::shared_ptr<int>>);

Current Behavior

static_assert(!std::is_same_v<pcl::shared_ptr<int>, std::shared_ptr<int>>);
static_assert(std::is_same_v<pcl::shared_ptr<int>, boost::shared_ptr<int>>);

Possible Solution

Start with

template <class T>
- using shared_ptr = boost::shared_ptr<T>;
+ using shared_ptr = std::shared_ptr<T>;

and resolve compilation errors.

EDIT:
Needs #3754
