Desugar default methods if required 

Desugar default methods if requested by LOCAL_MIN_SDK_VERSION < 26.
Also remove --desugar_try_with_resources_if_needed=false, it is no
longer necessary if we always proguard against frameworks.jar.
Fixes d8 issues when it sees unexpected default methods that dx
was passing through.

Test: m checkbuild
