RFR: 8344093: Implementation of JEP XXX: Deprecate the 32-bit x86 Port for Removal

[Aleksey Shipilev]

WIP, as the JEP is still not targeted. We can review code meanwhile.

Additional testing:
 - [x] Linux x86-32 build configure fails by default
 - [x] Linux x86-32 build configures well with `--enable-deprecated-ports=yes`
 - [ ] GHA
