Move lld.exe (windows) and add dependent library libwinpthread-1.dll

Move lld.exe to lld-bin directory; add lld-bin/libwinpthread-1.dll; add
trampoline.

Best practice is to ship necessary libraries of expected versions along
with build tools, rather than requiring them to be found elsewhere.

lld.exe depends on libwinpthread-1.dll and windows looks for it in the
same directory as lld.exe.  Unfortunately, there's already a 32-bit
libwinpthread-1.dll at the tool root (used by 32-bit executables at
the tool root), and lld.exe is a 64-bit executable, so it needs its own
directory and its own library.

In the old location of lld.exe, we add a trampoline executable (a build
artifact) in lld-bin; this means Gradle, which invokes lld.exe in the old
location, does not have to change.
