node:process — argv0/execPath/title not exposed as string properties

[proggeramlug]

process.argv0/execPath/title read as a number instead of a string. expr_member.rs handles argv/platform; these need analogous arms + runtime values. Repro: node-suite/process/props/string-props. Part of #793.

Fixed by #1371 — process.argv0/execPath/title now string properties (node-suite/process/props/string-props PASSES).

Reopening: the #1371 PR (which closed this) was merged INTO the #1331 PR branch, not into main. When the #1331 reconstruction rebased onto current main, the fix was dropped. Tracking this until either a separate fix PR lands or #1371's content is reopened.
