Revert "Temporarily Revert "[clangd] Add Random Forest runtime for code completion."" We intend to replace heuristics based code completion ranking with a Decision Forest Model. This patch introduces a format for representing the model and an inference runtime that is code-generated at build time. - Forest.json contains all the trees as an array of trees. - Features.json describes the features to be used. - Codegen file takes the above two files and generates CompletionModel containing Feature struct and corresponding Evaluate function. The Evaluate function maps a feature to a real number describing the relevance of this candidate. - The codegen is part of build system and these files are generated at build time. - Proposes a way to test the generated runtime using a test model. - Replicates the model structure in unittests. - unittest tests both the test model (for correct tree traversal) and the real model (for sanity). This reverts commit 549e55b3d5634870aa9d42135f51ad46a6a0e347.

# Run the Completion Model Codegenerator on the model present in the
# ${model} directory.
# Produces a pair of files called ${filename}.h and ${filename}.cpp in the
# ${CMAKE_CURRENT_BINARY_DIR}. The generated header
# will define a C++ class called ${cpp_class} - which may be a
# namespace-qualified class name.
Make clangd CompletionModel not depend on directory layout. The current code accounts for two possible layouts, but there is at least a third supported layout: clang-tools-extra may also be checked out as clang/tools/extra with the releases, which was not yet handled. Rather than treating that as a special case, use the location of CompletionModel.cmake to handle all three cases. This should address the problems that prompted D96787 and the problems that prompted the proposed revert D100625. Reviewed By: usaxena95 Differential Revision: https://reviews.llvm.org/D101851

Make clangd CompletionModel usable even with non-standard (but supported) layout llvm supports specifying a non-standard layout where each project lies in its own place. Do not assume a fixed layout and use the appropriate cmake variable instead. Differential Revision: https://reviews.llvm.org/D96787
