[boost-container] Fix deps and emscripten (#38806)

Fixes #38679. ([No longer uses
Boost::static_assert.](https://www.boost.org/doc/libs/1_85_0/doc/html/container/release_notes.html#container.release_notes.release_notes_boost_1_85_00))
Fixes #38469. (Needs threads, so [emscripten needs to use
`-pthread`](https://emscripten.org/docs/porting/pthreads.html#compiling-with-pthreads-enabled).)
Change homepage link to something more useful. The update to the
generator script and the other ports will be in a separate PR.
