OpenSSL 3.0 for 14.0-RELEASE: issues with 1.x/3.x symbol clashing, ports linking against base OpenSSL, ports that don't compile/link against OpenSSL 3, etc

Hello,
	One of the must-haves for 14.0-RELEASE is the introduction of OpenSSL 3.0 into the base system. This is a must because, in short, OpenSSL 1.1 is no longer supported as of 09/26/2023 [1].

	I am proposing OpenSSL be made private along with all dependent libraries, for the following reasons:
	1. More than a handful of core ports, e.g., security/py-cryptography [2] [3], still do not support OpenSSL 3.0.
		i. If other dependent ports (like lang/python38, etc) move to OpenSSL 3, the distributed modules would break on load due to clashing symbols if the right mix of modules were dlopen’ed in a specific order (importing ssl, then importing hazmat’s crypto would fail).
		ii. Such ports should be deprecated/marked broken as I’ve recommended on the 3.0 exp-run PR [4].
	2. OpenSSL 1.1 and 3.0 have clashing symbols, which makes linking in both libraries at runtime impossible without resorting to a number of linker tricks hiding the namespaces using symbol prefixing of public symbols, etc.

	The libraries which would need to be made private are as follows:
	- kerberos
	- libarchive
	- libbsnmp
	- libfetch [5]
	- libgeli
	- libldns
	- libmp
	- libradius
	- libunbound

	I realize I’m jumping to a prescribed solution without additional discussion, but I’ve been doing offline analysis related to uplifting code from OpenSSL 1.x to 3.x over the last several months and this is the general prescribed solution I’ve come to which is needed for $work. My perspective might have some blind spots and some of the discussion done over IRC and might need to be rehashed here for historical reference/to widen the discussion for alternate solutions that don’t have the degree of tunnel vision which the solution I’m employing at $work requires.
	I’ve tried to include some of the previously involved parties so they can chime in.
Thank you,

3. The reason why it hasn’t been upgraded is because newer versions require rustc to build, which apparently doesn’t work on QEMU builders due to missing emulation support: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=254853 <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=254853> .

5. If I remember correctly, some folks suggested that making libfetch private wasn’t required since the only port that required it was ports-mgmt/pkg, but I haven’t validated this claim.
