Merge bitcoin/bitcoin#32665: depends: Bump boost to 1.88.0 and use new CMake buildsystem

6c2538d5bf depends: Bump boost to 1.88.0 and use new CMake buildsystem (Cory Fields)

Pull request description:

  Originally #30434.

  This has a few advantages over the old method of simply copying headers:
  - Installs proper CMake files which can be picked up by our buildsystem
  - Only installs necessary headers, not all of Boost

+cmake: Add `BOOST_TEST_HEADERS_ONLY` configuration variable
+
+This change allows the build to be configured to install only the
+Boost.Test headers required for using the headers-only variant of the
+Unit Test Framework.
