[CMake] Provide Findzstd module
This module is used to find the system zstd library. The imported
targets intentionally use the same name as the generate zstd config
CMake file so these can be used interchangeably.
Differential Revision: https://reviews.llvm.org/D134990
(cherry picked from commit 2d4fd0b6d5d5582ebb8b521d807104235d67aee4)
