Patch started out for working around compiler warnings in BearSSL latest
tarball release v0.6 (2018-08-14) and Apple clang 14 with CMake.
Then turned into patching CMake and `Makefile.mk` builds to use
`-isystem` instead `-I` when adding header directories for
dependencies. This avoids compiler warnings in dependency headers,
syncing behaviour with autotools.
Also:
- `Makefile.mk`: add support for BearSSL.
- delete warning suppression for mbedTLS headers. No longer necessary
after this patch.

Silenced BearSSL warnings:

(These warnings were fixed in BearSSL Git master in 2019 via

ecdf89770ee82dfea6186fb4369cff3d06cd852e.)
Also these two cases, which are caused by an unidentified component
(outside curl) cranking up MSVC warnings in external headers to `/W4`
when ZLIB is deselected:
