The Find and ReverseFind methods for WideString, WideStringC,
ByteString, and ByteStringC have been converted from returning a raw
FX_STRSIZE, to returning Optional<FX_STRSIZE>, so that success/failure
can be indicated without using FX_STRNPOS.
This allows for removing FX_STRNPOS and by association makes the
conversion of FX_STRSIZE to size_t easier, since it forces checking
the return value of Find to be explictly done as well as taking the
error value out of the range of FX_STRSIZE.
New Contains methods have been added for cases where the success or
failure is all the call site to Find cared about, and the actual
position was ignored.

This method duplicates the behaviour of the const [] operator and
doesn't offer any additional safety. Folding them into one
implementation.
SetAt is retained, since implementing the non-const [] operator to
replace SetAt has potential performance concerns. Specifically many
non-obvious cases of reading an element using [] will cause a realloc
& copy.

The existing behaviour was to clamp the provided index to the valid
bounds. This would lead to programming errors being hidden, since
inserting would still do something even if the index calculation was
wrong. The behaviour of these methods has been changed to instead
early return when this occurs, returning the old length value. The
caller can check if the call to Insert actually did anything by
comparing the returned value to the length before calling insert.
All of the existing calls to Insert have been tested by running all of
the tests with asserts in the Insert method to check the index is in
bounds. Additionally the call sites have been manually inspected. The
majority of them are of the form Insert(0, foo) and the rest tend to
be in a loop advancing from 0 to length.
Convenience methods InsertAtFront/InsertAtBack have been added to
handle calling Insert when the intent is for the character to be added
to the beginning or end of the string. Existing call sites to Insert
that do this have been converted.
This work was originally being performed to check if there would be
any issues in these methods with making FX_STRSIZE unsigned.

Currently Find() and other methods that return a FX_STRSIZE return -1
to indicate error/failure. This means that there is a lot of magic
numbers and magic checks floating around. The standard library for
similar operations uses a npos constant. This CL implements
FX_STRNPOS, and replaces usages of magic number checking. It also does
some type cleanup along the way where it was obvious that FX_STRSIZE
should be being used.
Removing the magic numbers should make eventually changing FX_STRSIZE
to be unsigned easier in the future.

The various string/byte classes support Mid(), Left(), and Right() for
extracting substrings. Mid() can handle all possible cases, but Left()
and Right() are useful for common cases and more explicit about what
is going on.
Calls like Mid(offset, length - offset) can be converted to
Right(length - offset). Calls like Mid(0, length) can be converted to
Left(length).
If the substring being extracted does not extend all the way to one of
the edges of the string, then Mid() still needs to be used.

This support is being removed from CFX_ByteString, CFX_ByteStringC,
CFX_WideString, and CFX_WideStringC. This standardizes all of these
classes to only have one Mid method that takes in 2 params, offset and
count. Count now must be positive. The old behaviour of calculating
the length for the user if -1 is passed in for the count has been
removed. This work is in preperation for converting these classes to
not accept negative lengths anywhere and thus make the underlying size
type unsigned.

There are currently three ways to assert in the code (ASSERT, FXSYS_assert and

be overridden if the platform requies and we can pickup the Chromium version
if it has already been defined in the build.
This does change behaviour. Currently FXSYS_assert is always defined but ASSERT

builds. That will no longer happen.
