Revert "Roll src/buildtools/third_party/libc++/trunk/ b1269813e..1a637088a (287 commits)"

This reverts commit 49792f173a1be0abefae749285e8590e84889fb2.

Reason for revert: Create revert as part of the procedure to update libassistant per wutao's instructions in https://crrev.com/c/3702740.

Original change's description:
> Roll src/buildtools/third_party/libc++/trunk/ b1269813e..1a637088a (287 commits)
>
> In order to get the chromeos buidls to pass (broken by this CL due to
> libassistant), we need to first submit this CL so libassistant can pick
> up buildtools, revert this CL, and then resubmit once libassistant has
> been updated.
>
> Additionally, reenable libc++ debug mode with ThinLTO since this is
> resolved by https://reviews.llvm.org/D122941.
>
> Additional changes to get this to build:
> * Regenerate absl
> * Regenerate gvr shims
> * Update #pragma clang_max_tokens as necessary
