Improve QtGP error messages for nonexisting directoriesHEADdev

With the current implementation the error messages for typoing the three
user-defined paths in gradle.properties are terrible. If the user sets
qt.path to a nonexisting directory:

* What went wrong:
Execution failed for task ':app:QtBuildTask'.
> No Qt for Android kit found from:

This is the best one, as at least it shows that something is wrong
finding Q4A.

For a wrong qt.abiPath the abiPath is ignored and a normal multi-ABI
build is started instead without showing any error. Probably not the
desired course of action.

And if qt.projectPath is wrong:

* What went wrong:
A problem occurred configuring project ':app'.
> Could not create task ':app:QtBuildTask'.
   > Cannot cast object '' with class 'java.lang.String' to class
   'java.io.File'

This all stems from the getAbsolutePath function returning an empty
string if the path doesn't exist. By removing that we can get better
error messages from later down in the chain or from gradle:

* What went wrong:
Execution failed for task ':app:QtBuildTask'.
> No Qt for Android kit found from: /Users/ollivuolteenaho/Qt/not-here

* What went wrong:
Execution failed for task ':app:QtBuildTask'.
> No Core.json file found under /Users/ollivuolteenaho/Qt/not-here/
  android_arm64_v8a/modules/Core.json.

* What went wrong:
A problem was found with the configuration of task ':app:QtBuildTask'
(type 'QtBuildTask').
  - In plugin 'org.qtproject.qt.gradleplugin' type
  'org.qtproject.qt.gradleplugin.QtBuildTask' property 'projectPath'
  specifies directory '/Users/ollivuolteenaho/Qt/Examples/Qt-6.9.1/
  platforms/android/doesnt-exist' which doesn't exist.

We could also raise an error QtGradlePlugin.yaml:buildTask but a problem
with that approach is that it also blocks "gradle clean", because the
error is in the plugin configuration stage at that point. So this seems
like the simple quick fix to make everything more sensible and future
improvements can be handled through QTTA-342.
