* Migrate ILSpy.AddIn.VS2022 to SDK-style VSIX project
* Retire the legacy VS2017/2019 ILSpy add-in
* Build the VS extension via dotnet build on the slnx
* Inline ILSpy.AddIn.Shared into ILSpy.AddIn.VS2022
* Restore the VS add-in menus broken by the SDK-style migration
ILSpy targets net10.0, not net10.0-windows; the VS add-in build paths, the
installer output dir, the local-dev publish script, and the VS Code launch
config still referenced the old net10.0-windows layout. Align them with the
actual TFM, matching publish.ps1 and the build workflow.

Replace the Windows-only .bat helpers (clean / debugbuild / releasebuild /
restore / updatedeps and BuildTools/format) with cross-platform pwsh
scripts at the repo root: restore.ps1, build.ps1 (-Configuration), clean.ps1,
updatedeps.ps1 and BuildTools/format.ps1, alongside the existing publish.ps1.
Enable a packages.lock.json for every project by hoisting
RestorePackagesWithLockFile into the root Directory.Build.props (the four
core libraries set it individually before) and commit the generated locks,
so restores are repeatable and CI can cache packages off them.
Cache the NuGet packages folder in the three setup-dotnet workflows
(build-ilspy, build-frontends, codeql-analysis), keyed on the lock files
per the setup-dotnet caching guidance.
Scope the Debug "Verify package contents" check to the *.filelist outputs
it actually generates. A project's packages.lock.json is keyed only by
(framework, RID), with no host-OS axis, so a lock produced on Linux
legitimately differs from one produced on Windows whenever an OS-conditional
PackageReference applies (Debug+Windows pulls Microsoft.DiaSymReader*). The
Windows restore then rewrites those locks; that churn must not fail a step
whose job is to police the VSIX/MSI file lists.
Also drop the dead ILSpy.BamlDecompiler publish line from
publishlocaldev.ps1, mirroring the earlier publish.ps1 fix.
