Allow turning off stack trace collection in Guice.

By setting guice_include_stack_traces flag OFF, Guice does not collect stack traces for identifying the declaring source of a binding. Instead it uses the first non-skipped module class name from the modules stack. As a result, in some cases, error messages can be slightly different with this flag. For example, the file name and line number are not always available.

A sample error message with this flag :

Guice creation errors:
1) Received null converting foo (bound at com.google.inject.TypeConversionTest.configure(Unknown Source) (via modules: com.google.inject.TypeConversionTest -> com.google.inject.TypeConversionTest)) to java.util.Date
using CustomConverter which matches only(java.util.Date) (bound at com.google.inject.TypeConversionTest.configure(Unknown Source) (via modules: com.google.inject.TypeConversionTest -> com.google.inject.TypeConversionTest -> com.google.inject.TypeConversionTest)).
while locating java.util.Date annotated with @com.google.inject.TypeConversionTest()
for field at com.google.inject.TypeConversionTest.date(TypeConversionTest.java:478)
at com.google.inject.TypeConversionTest.configure(Unknown Source) (via modules: com.google.inject.TypeConversionTest -> com.google.inject.TypeConversionTest)

This also changes the DEFAULT flag name to ONLY_FOR_DECLARTION_SOURCE.
Adds InternalFlags.getIncludeStackTraceOption() to wrap system property access.
