feat(libScePad): declare two exports by their hash-verified names

[parl0v]

What

Declares 2 exports by name: a virtual-device trigger state and an Aston device-information export. Each is a throwing stub (NotImplemented_nid_no_patch) declared without parameters, with an Unknown function info entry in its library's technical debt file.

Library	NID	Name	zecoxao/sce_symbols
libScePad	wMvV6XbeFd0	scePadVirtualDeviceInsertTriggerState	#23
libScePad	ybhL4IoyGZA	scePadAstonGetDeviceInformation	#23

The names come from the shared NID database, where I added them (zecoxao/sce_symbols #22 and #23). Each name hashes to its NID with tools/nid_names.py compute_nid, and the library is the module that exports the NID in the 10.01 system modules.

No title I know of imports these yet, so nothing calls them today. With them declared, a title that does import one resolves it by name and stops with that name in the NotImplemented message instead of an unresolved NID at load. Implementations can then replace the stubs one by one.

Tested

• Windows 10 19045, MinGW-w64 GCC 15.2: the libs target builds; tools/check_conventions.py --base origin/main passes.
• Every name re-hashed against its NID before the commit.

Checklist

• Based on current main; no other open PR implements the same functions
• One topic per PR; follow-ups go in a new PR
• No comments in code except technical debt
• Unimplemented paths throw (NotImplemented_nid_no_patch); silent stubs are listed under Silent stubs in their library's technical debt file
• No notes, investigation .md files or images added to the repository (attach them to this PR)
• New third-party code is a submodule built from source
• Generic behaviour, not specific to one title
• Depends on: none
• Unblocks: none
• AI-assisted: yes

[github-actions]

Other open pull requests touch the same code. Merging one will break the other, or both implement the same thing. If this one builds on them, list them in Depends on.

Same situation as #5123 in this series (see the review there): the names hash correctly, but no title imports these exports yet, and export-only PRs without a title that reaches the export on main have been closed (#1205, #1208, #950). Keeping the names in sce_symbols and reopening once a title's log shows one of them would match current review practice.

Closing: no title is known to reach this. With the queue at 700+ open PRs, please hold off on new PRs that don't name a title needing the change until it's down. If a title stops on this on current main, reopen with the title ID and the log line.
