Efcore: SuppressForeignKeyEnforcement is missing from SqliteDbContextOptionsBuilder

[StefanSimion]

SuppressForeignKeyEnforcement is missing from SqliteDbContextOptionsBuilder in Microsoft.EntityFrameworkCore.Sqlite version 3.0.0-preview8.19405.11.

Steps to reproduce

```c#
DbContextOptionsBuilder optionBuilder = new DbContextOptionsBuilder();

optionBuilder.UseSqlite(connectionString, x => x.SuppressForeignKeyEnforcement());
```
This code worked fine with Microsoft.EntityFrameworkCore.Sqlite version 2.2.6.
Upgrade Microsoft.EntityFrameworkCore.Sqlite version 2.2.6 to 3.0.0-preview8.19405.11 and SuppressForeignKeyEnforcement is not there anymore

Further technical details

EF Core version: 2.2.6 and 3.0.0-preview8.19405.11
Database Provider: Microsoft.EntityFrameworkCore.Sqlite
Operating system: Windows 10
IDE: Visual Studio 2019 16.2.3

[StefanSimion]

Because FK enforcement is switched on by default starting with EF Core 3.0-preview 3, I removed x => x.SuppressForeignKeyEnforcement() part and everything works fine now.

Thank you for your prompt reply @ErikEJ
