Deprecate running an application in the Maven JVM

Browse Source 
This commit deprecates the "fork" property so that the application

the Gradle plugin, and simplifies the lifecycle of certain features that
would not work in a non-forked process.

Closes gh-30479

If you need to specify some JVM arguments (that is for debugging purposes), you can use the `jvmArguments` parameter, see <<run.examples.debug,Debug the application>> for more details.
There is also explicit support for <<run.examples.system-properties,system properties>> and <<run.examples.environment-variables,environment variables>>.
As enabling a profile is quite common, there is dedicated `profiles` property that offers a shortcut for `-Dspring-boot.run.jvmArguments="-Dspring.profiles.active=dev"`, see <<run.examples.specify-active-profiles,Specify active profiles>>.
Although this is not recommended, it is possible to execute the application directly from the Maven JVM by disabling the `fork` property.

Doing so means that the `jvmArguments`, `systemPropertyVariables`, `environmentVariables` and `agents` options are ignored.
