[cmake] Fix host tools build in when LLVM_EXPERIMENTAL_TARGETS_TO_BUILD is set
r320413 triggered cmake configure failures when building with
-DLLVM_OPTIMIZED_TABLEGEN=True and with LLVM_EXPERIMENTAL_TARGETS_TO_BUILD set
(e.g. to RISCV). This is because that patch moved to passing through
LLVM_TARGETS_TO_BUILD, and at that point LLVM_EXPERIMENTAL_TARGETS_TO_BUILD
has been merged in to it. LLVM_EXPERIMENTAL_TARGETS_TO_BUILD must be also be
passed through to avoid errors like below:
-- Constructing LLVMBuild project information
CMake Error at CMakeLists.txt:682 (message):
The target `RISCV' does not exist.
It should be one of
AArch64;AMDGPU;ARM;BPF;Hexagon;Lanai;Mips;MSP430;NVPTX;PowerPC;Sparc;SystemZ;X86;XCore
-- Configuring incomplete, errors occurred!
