Modify `cmInstallGenerator` to have a `cmDiagnosticContext` instead of
just a `cmListFileBacktrace`. Create helpers to obtain a state capture
that includes `CMD_INSTALL_ABSOLUTE_DESTINATION`. Modify most subclasses
(namely, ones that have a `DESTINATION`) to use this new state capture.
This fixes a limitation identified when 39a56136a3 (Diagnostic: Add warn
or error on absolute install paths, 2026-03-25) added the aforementioned
diagnostic, that the install generator(s) no longer have access to the
diagnostic state as of the `install` invocation which ultimately caused
the diagnostic if that scope is not the top-most scope of the current
subdirectory.
Note that some of the generators which capture context have not actually
implemented the diagnostic yet.
