Revert of Make GrDrawContext::internalDrawPath cons up its own GrPipelineBuilder (patchset #3 id:40001 of https://codereview.chromium.org/1730903007/ )

Reason for revert:
Got a GL-related crash in nanobench:

https://uberchromegw.corp.google.com/i/client.skia.android/builders/Perf-Android-GCC-Nexus10-GPU-MaliT604-Arm7-Release/builds/3815/steps/nanobench/logs/stdio

Given we're about to branch and this is the only GL-related change in the blamelist, I'm going to assume this is responsible and revert.

> Hopefully, this better defines (and reduces) the lifetime and reuse of GrPipelineBuilder objects in GrDrawContext.
