[release/10.0] Switch Microsoft.Data.Sqlite and EFCore.Sqlite to SQLite3MC.PCLRaw.bundle (backport #38402, #36551)

[ViveliDuCh]

Backports the SQLite native bundle change (#38402, merged in 11.0 preview 6) to release/10.0. See #38402 for the full rationale and dotnet/EntityFramework.Docs#5385 for the breaking-change docs.

Because release/10.0 did not yet have the SQLitePCLRaw 3.x update (#36551 / #36535), this backport combines both changes:

• SQLitePCLRaw 3.x — bumps SQLitePCLRawVersion to 3.0.3. The crypto and OS-provided bundles (bundle_e_sqlcipher, bundle_e_sqlite3mc, bundle_sqlite3, bundle_winsqlite3) are no longer published, so the affected test projects move to the SQLitePCLRaw.provider.* packages and the e_sqlcipher/e_sqlite3mc test projects are removed.
• SQLite3MC bundle — Microsoft.Data.Sqlite and Microsoft.EntityFrameworkCore.Sqlite now reference SQLite3MC.PCLRaw.bundle (2.3.5) instead of SQLitePCLRaw.bundle_e_sqlite3, shipping an encryption-capable (SQLite3 Multiple Ciphers) native build by default.
• Test coverage — adds a Microsoft.Data.Sqlite.sqlite3mc.Tests project and switches EFCore.Sqlite.FunctionalTests / EFCore.Design.Tests to SQLite3MC.PCLRaw.bundle so CI exercises the shipped bundle.

User-facing breaking-change behavior and migration guidance are documented in dotnet/EntityFramework.Docs#5385.

Pull request overview

Backports the SQLite native-bundle switch and SQLitePCLRaw 3.x packaging changes to release/10.0, updating shipped Sqlite packages to use the SQLite3MC bundle (encryption-capable) by default and adjusting test coverage/projects accordingly.

Changes:

• Updated EFCore.Sqlite and Microsoft.Data.Sqlite to reference SQLite3MC.PCLRaw.bundle, and added the corresponding centralized version plumbing.
• Updated/reshaped the Microsoft.Data.Sqlite test matrix for SQLitePCLRaw 3.x (provider packages for OS-provided SQLite; removed deprecated crypto/OS bundle-based test projects; added sqlite3mc tests).
• Updated solutions/filters and test projects (EFCore.Sqlite.FunctionalTests/EFCore.Design.Tests) to exercise the shipped SQLite3MC bundle in CI.
