this change should silence the warning when building Ceph with Boost 1.82:
```
CMake Warning at cmake/modules/FindBoost.cmake:1384 (message):
New Boost version may have incorrect or missing dependencies and imported
targets
Call Stack (most recent call first):
cmake/modules/FindBoost.cmake:1507 (_Boost_COMPONENT_DEPENDENCIES)
cmake/modules/FindBoost.cmake:2125 (_Boost_MISSING_DEPENDENCIES)
CMakeLists.txt:687 (find_package)
```
despite that 244c5ebb added boost to `_Boost_KNOWN_VERSIONS`, it was
not enough. would be better to sync up the CMake upstream for an updated
version of this file like we did before.
in this change
* syncs this file with
897a149067/Modules/FindBoost.cmak
* re-apply the change of 06824bc1ec

cmake: adapt FindBoost.cmake to our needs
the vanilla FindBoost.cmake pulled from cmake has couple assumptions
which do not hold in our environment. so address them case by case.

CMake CMP0093 was introduced by CMake 3.15, but we only require CMake
v3.10.2. so use the old `Boost_VERSION_MACRO` variable by default,
unless specified otherwise.

CMake CMP0074 was introduced by CMake 3.12, but we only require CMake
v3.10.2. so default to check `Boost_ROOT` unless specified otherwise.

the FindBoost.cmake shipped by cmake 3.5.1 is not new enough to identify
the dependencies of boost 1.63 and up. so we need to copy the
FindBoost.cmake from cmake upstream. it supports up to boost 1.68.
