Many improvements to LeakChecker builds

The presence of the LeakChecker is now detected when possible. GCC
users using LeakChecker in standalone mode still need to use
-DLEAK_CHECKER. This is now documented in the header.

The hacky targets used for testing leak checking have been removed in
favor of testing in AddressSanitizer mode on Kokoro.

Fixes #885
Fixes #1153
