`LLVM_TOOL_LLD_BUILD` is required for `COMPILER_RT_HAS_LLD` to be set which impacts tests in the following ways:

- This sets `config.has_lld` in various lit files. This allows hwasan tests to run for arm runtimes and sets the feature `lld-available` which is required for a couple of tests.
- Adds an "lld variant" of test suites for various sanitizers like msan that essentially run a suite of msan tests, but explicitly linked with lld.
