1. WoA LLVM bots config update to improve build time …

   Since llvm#252 we have got increased build times on WoA build bots.
   Also WoA 2 stage bot does not collapse the queue because it is
   not configured to always do a clean build. This patch tries to
   fix above issues.
   
   On both single and 2 stage bots:
   - Set `LLVM_TARGETS_TO_BUILD` to 'ARM;AArch64;X86'. We only care
     about these targets on windows.
   
   On 2 stage bot:
   - Set stage 1 LLVM_TARGETS_TO_BUILD to AArch64 only.
   - Set extra_stage2_cmake_args which overrides extra_cmake_flags.
   - Disable flang build on stage1 by setting checkout_flang=False.
   - Enabled `LLVM_ENABLE_PROJECTS=flang;mlir` for stage 2.
   - Switched to a clean build (`clean=True`) for collapsing queue.
   - Like stage 1 set stage 2 CLANG_DEFAULT_LINKER to lld. This makes
     sure just built lld is used by just built clang as default linker.
