Set system properties to suppress warnings

[griffio]

fixes #sqldelight/sqldelight#5749

Add default values from https://github.com/JetBrains/intellij-community/blob/master/platform/util/resources/misc/registry.properties

Tested with SqlDelight compiler tests - with and without changes to verify that warnings are gone

Changes made to sql-psi can be tested with SqlDelight by adding in settings.gradle

includeBuild('../sql-psi') {
  dependencySubstitution {
    substitute(module("app.cash.sql-psi:core")).using(project(":core"))
    substitute(module("app.cash.sql-psi:environment")).using(project(":environment"))
  }
}

Verify that it actually fixes the output for users when SqlDelight is compiling in a project - The warnings do not appear when doing a clean build using snapshot build

Task :generateMainSampleMigrations

There does appear to be some other place in this build (unrelated?) that has two of the warnings appear
