Remove the mono12.0 family of well-known monikers and toolchains

CsProjNetToolchain.ValidateAsync always rejects Mono, MonoWasm, and
MonoWasmAot runtimes targeting .NET 12 and later, so the well-known
mono12.0, monowasm12.0, and monowasmaot12.0 monikers and their cached
runtime and toolchain singletons are unreachable. Parsing an explicit
version still resolves through the uncached fallback.
