Zygote: Allow arbitrary-length wrap property names

Browse Source 
The restriction on system property key length has been lifted.
Update the invoke-with code to first check the full-length property.
Then fall back to the truncated version for backwards-compatibility.

Bug: 37276041

Test: m
Test: manual with long package name (Maps)
(cherry picked from commit 4c88a8c684)
