Currently, `printHelp` behaves differently for options that:
* do not define `HelpText` (such options _are not printed_), and
* define its `HelpText` as `HelpText<"">` (such options _are printed_).
In practice, both approaches lead to no help text and `printHelp` should
treat them consistently. This patch addresses that by making
`printHelpt` check the length of the help text to be printed.
All affected tests have been updated accordingly. The option definitions
for llvm-cvtres have been updated with a short description or "Not
implemented" for options that are ignored by the tool.

For lld, pass in Config->Timestamp (which is set based on lld's
/timestamp: and /Brepro flags). Since the writeWindowsResourceCOFF()
data is only used in-memory by LLD and the obj's timestamp isn't used
for anything in the output, this doesn't change behavior.
For llvm-cvtres, add an optional /timestamp: parameter, and use the
current behavior of calling time() if the parameter is not passed in.
This doesn't really change observable behavior (unless someone passes
/timestamp: to llvm-cvtres, which wasn't possible before), but it
removes the last unqualified call to time() from llvm/lib, which seems
like a good thing.

This marks the beginning of an effort to port remaining
MSVC toolchain miscellaneous utilities to all platforms.
Currently clang-cl shells out to certain additional tools
such as the IDL compiler, resource compiler, and a few
other tools, but as these tools are Windows-only it
limits the ability of clang to target Windows on other
platforms. having a full suite of these tools directly
in LLVM should eliminate this constraint.
The current implementation provides no actual functionality,
it is just an empty skeleton executable for the purposes
of making incremental changes.
