Update configuration for llvm-clang-x86_64-expensive-checks-ubuntu* builders (#451)

* switch to clang-21/lld-21 instead of gcc/ld.gold to speed up the
builds and avoid the ld.gold liner warnings related with unsupported
DWARF version.
* switch to release build to speed up the builds because of clang/llvm
table-gen tool.

Also moved to 'UnifiedTreeBuilder.getCmakeExBuildFactory' factory.
