[Plugin] Make benchmark compilation name unique for each target

Kotlin plugin produces IR and WASM executables in build/compileSync/compilationName directory.
Thus, if benchmark compilation name of two targets are equal,
in parallel execution of tasks they overwrite each other,
leading to Gradle task configuration error:

Task ':examples:kotlin-multiplatform:jsIrBuiltInBenchmarkBenchmarkProductionExecutableCompileSync' uses this output of task ':examples:kotlin-multiplatform:compileBenchmarkProductionExecutableKotlinWasm' without declaring an explicit or implicit dependency.
