Revert of Create a single command buffer for GrInOrderDrawBuffer (patchset #14 id:1050001 of https://codereview.chromium.org/628453002/)

Reason for revert:
New test failing on Android: http://build.chromium.org/p/client.skia.android/builders/Test-Android-Nexus7-Tegra3-Arm7-Release/builds/89/steps/dm/logs/stdio

Original issue's description:
> Adds a GrTBaseList class that GrInOrderDrawBuffer uses to allocate
> all its commands interleaved in contiguous memory. GrTBaseList also
> supports extra data associated with objects, so we can store arrays
> inline without having to call malloc().
>
> Committed: https://skia.googlesource.com/skia/+/47c844aaba81e5a29c773b660e1d6062c766d253
