Summary:
Support formatv of TimePoint with strftime-style formats.
Extensions for millis/micros/nanos are added.
Inital use case is HH:MM:SS.MMM timestamps in clangd logs.

Summary:
The formatter has three knobs:
- the user can choose which time unit to use for formatting (default: whatever is the unit of the input)
- he can choose whether the unit gets displayed (default: yes)
- he can affect the way the number itself is formatted via standard number formatting options (default:default)

This is a resubmission of r284590. The mingw build should be fixed now. The
problem was we were matching time_t with _localtime_64s, which was incorrect on
_USE_32BIT_TIME_T systems. Instead I use localtime_s, which should always
evaluate to the correct function.

This reverts commit r284590 as it fails on the mingw buildbot. I think I know the
fix, but I cannot test it right now. Will reapply when I verify it works ok.
This reverts r284590.

Summary:
std::chrono mostly covers the functionality of llvm::sys::TimeValue and
lldb_private::TimeValue. This header adds a bit of utility functions and
typedefs, which make the usage of the library and porting code from TimeValues
easier.
Rationale:
- TimePoint typedef - precision of system_clock is implementation defined -
using a well-defined precision helps maintain consistency between platforms,
makes it interact better with existing TimeValue classes, and avoids cases
there a time point is implicitly convertible to a specific precision on some
platforms but not on others.
- system_clock::to_time_t only accepts time_points with the default system
precision (even though time_t has only second precision on all platforms we
support). To avoid the need for explicit casts, I have added a toTimeT()
wrapper function. toTimePoint(time_t) was not strictly necessary, but I have
added it for symmetry.
