There's many instances in clang tidy checks where owning strings are used when we already have a stable string from the options, so using a StringRef makes much more sense.

This change adds an option to disable warnings from the
cppcoreguidelines-narrowing-conversions check on integer to floating-
point conversions which may be narrowing.
An example of a case where this might be useful:
```
std::vector<double> v = {1, 2, 3, 4};
double mean = std::accumulate(v.cbegin(), v.cend(), 0.0) / v.size();
```
The conversion from std::size_t to double is technically narrowing on
64-bit systems, but v almost certainly does not have enough elements
for this to be a problem.
This option would allow the cppcoreguidelines-narrowing-conversions
check to be enabled on codebases which might otherwise turn it off
because of cases like the above.
mixed integer and floating point types with WarnOnEquivalentBitWidth=0.
Also standardize control flow of handleX conversion functions to make it easier to be consistent.

Within clang-tidy's NarrowingConversionsCheck.
* Allow opt-out of some common occurring patterns, such as:
- Implicit casts between types of equivalent bit widths.
- Implicit casts occurring from the return of a ::size() method.
- Implicit casts on size_type and difference_type.
* Allow opt-in of errors within template instantiations.
This will help projects adopt these guidelines iteratively.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
Checks for narrowing conversions, e.g.
int i = 0;
i += 0.1;
This has what some might consider false positives for:
i += ceil(d);
