Codechange: Replace C-style casts to size_t with static_cast. (#12455) 
* Codechange: Replace C-style casts to size_t with static_cast.

This touches only simple value-type casts.

* Codechange: Replace static_cast<size_t>(-1) with SIZE_MAX

Fix: Memory leak in ICUParagraphLayout::NextLine() (#11895) 
This function calls icu::BreakIterator::createLineInstance() but does not clean up after it.

Instead use a static instance that is cloned (for thread-safety) and deleted as necessary.

Fix #11827: Make Layouter::GetCharPosition() aware of ligatures. (#11831) 
When ligatures happen the precise individual character position is not known, so instead return the previous position (which is that of the ligature.)

Peter Nelson ae575a7a5b Codechange: Store text run positions in vector of points.

Patric Stout 60399e17bd Codechange: C++-ify the Layouter and related functions 
They all now access a std::string_view, instead of a "const char *"
or std::string (in some cases).

Additionally, GetCharAtPosition and friends now return an index
instead of a "const char *", as it makes for a more clear interface.

Patric Stout 81d4fa6999 Feature: drop ICU-lx in favour of directly interfacing with harfbuzz 
This means we have RTL support again with ICU 58+. It makes use of:
- ICU for bidi-itemization
- ICU for script-itemization
- OpenTTD for style-itemization
- harfbuzz for shaping

Codechange: Improve LineCache queries (#9417) 
Adds the support to query the linecache without copying the string.
This uses a custom transparent comparator in conjunction with
a query type using a std::string_view.

Patric Stout 52d7e7d45e Codechange: ICU_LAYOUT is in reality ICU_LX (according to their CMake files) 
By naming it in a different way, things get a bit confusing.
Especially if we are switching to CMake, which autodetects these
things, we need to use the name the authors of ICU gave it; not
our interpertation of that name.

Michael Lutz 32ce1ce347 Add: [OSX] Text layout using the native CoreText API. 
By default, the native API will be used instead of ICU, but if ICU is
forced in using configure, it will take precedence.

Michael Lutz 768a31bfe3 Add: [Win32] Text layout using the native Windows Uniscribe library. 
Uniscribe is sometimes producing different results compared to ICU, especially
when RTL and LTR content is mixed. Comparing the results to other programs
(like editors or web browsers) leads me to believe that the result are at least
not worse than ICU and possibly better.
