Replace locking JNI array methods

Certain JNI methods utilize (PrimitiveCritical) a lock on the gc and
other JVM resources to avoid copying array sections. In AudioEffect, all
the arrays we wish to read are small, and not worth this cost.
Additionally, holding this lock while going into blocking calls can lead
to runtime issues.
