ShaderMetricsSystem spawns a lot of warnings (#5661)

Browse Source 
* ShaderMetricsSystem spawns a lot of warnings
when run Atom_RPI.Tests

Added @user@ path alias definition.

* When running unit tests, using AZ::Utils::GetProjectPath() will resolve
to something like:
"/data/workspace/o3de/build/linux/External/Atom-9a4d112b/RPI/Code/Cache"
The ShaderMetricSystem.cpp writes to the @user@ folder and the following
runtime error occurs:
"You may not alter data inside the asset cache.  Please check the call
stack and consider writing into the source asset folder instead."
"Attempted write location:
/data/workspace/o3de/build/linux/External/Atom-9a4d112b/RPI/Code/Cache/user/shadermetrics.json"
To avoid the error We use AZ::Test::GetEngineRootPath();
