[Upstream PR 3570] Test SQLite native parser extension assets

[adamziel]

Source: WordPress#3570

Status: open draft, conflicting, mergeStateStatus=DIRTY.

Findings:

• Bundles SQLite/native parser extension assets and CI workload.
• Most underlying extension-loader architecture has landed through [PHP] Support custom PHP.wasm extensions WordPress/wordpress-playground#3566, [PHP] Support extraFiles for custom PHP extensions WordPress/wordpress-playground#3580, Export SQLite auto-extension symbols for PHP.wasm side modules WordPress/wordpress-playground#3524, Export SQLite auto-extension symbols in Node PHP 8.4 JSPI artifact WordPress/wordpress-playground#3642, [PHP.wasm] Support web JSPI side module ABI exports WordPress/wordpress-playground#3647, and [PHP.wasm] Fix sqlite_markdown extension loading WordPress/wordpress-playground#3650.
• Trunk does not appear to have the wp-mysql-parser asset directory; the exact asset test may still be useful but the branch shape is stale.

Recommendation:
Do not merge as-is. Either close as superseded by the newer extension infrastructure or recreate as a narrow, current SQLite parser asset/test PR.

Closing as obsolete in its current branch shape: the extension-loader architecture has moved on. Recreate only as a narrow current-trunk SQLite parser asset/test PR if that coverage is still needed.
