[compiler-rt] Add ConsumeProbability and ConsumeFloatingPoint methods to FDP.
Summary:
Also slightly cleaned up the comments and changed the header's extension
back to `.h` as per comments on https://reviews.llvm.org/D65812.
New methods added:
* `ConsumeProbability` returns [0.0, 1.0] by consuming an unsigned integer value
from the input data and dividing that value by the integer's max value.
* `ConsumeFloatingPointInRange` returns a floating point value in the given
range. Relies on `ConsumeProbability` method. This method does not have the
limitation of `std::uniform_real_distribution` that requires the given range
to be <= the floating point type's max. If the range is too large, this
implementation will additionally call `ConsumeBool` to decide whether the
result will be in the first or the second half of the range.
* `ConsumeFloatingPoint` returns a floating point value in the range
`[std::numeric_limits<T>::lowest(), std::numeric_limits<T>::min()]`.
Tested on Linux, Mac, Windows.

[compiler-rt] Move FDP to include/fuzzer/FuzzedDataProvider.h for easier use.
Summary:
FuzzedDataProvider is a helper class for writing fuzz targets that fuzz
multple inputs simultaneously. The header is supposed to be used for fuzzing
engine agnostic fuzz targets (i.e. the same target can be used with libFuzzer,
AFL, honggfuzz, and other engines). The common thing though is that fuzz targets
are typically compiled with clang, as it provides all sanitizers as well as
different coverage instrumentation modes. Therefore, making this FDP class a
part of the compiler-rt installation package would make it easier to develop
and distribute fuzz targets across different projects, build systems, etc.
Some context also available in https://github.com/google/oss-fuzz/pull/2547.
This CL does not delete the header from `lib/fuzzer/utils` directory in order to
provide the downstream users some time for a smooth migration to the new
header location.

[libFuzzer] Improve FuzzedDataProvider helper.
Summary:
The following changes are made based on the feedback from Tim King:
- Removed default template parameters, to have less assumptions.
- Implemented `ConsumeBytesWithTerminator` method.
- Made `PickValueInArray` method work with `initializer_list` argument.
- Got rid of `data_type` type alias, that was redundant.
- Refactored `ConsumeBytes` logic into a private method for better code reuse.
- Replaced implementation defined unsigned to signed conversion.
- Fixed `ConsumeRandomLengthString` to always call `shrink_to_fit`.
- Clarified and fixed some commments.
- Applied clang-format to both the library and the unittest source.
Tested on Linux, Mac, Windows.

Add FuzzedDataProvider helper class / single header library.
Summary:
This class is useful for writing fuzz target that have multiple inputs.
Current CL imports the existing `FuzzedDataProvider` from Chromium
without any modifications. Feel free to review it thoroughly, if you're
interested, but I'd prefer changing the class in a follow up CL.
The CL also introduces an exhaustive test for the library, as the behavior
of `FuzzedDataProvider` must not change over time.
In follow up CLs I'm planning on changing some implementation details
(I can share a doc with some comments to be addressed). After that, we
will document how `FuzzedDataProvider` should be used.
I have tested this on Linux, Windows and Mac platforms.
