Update freetype to 2.12.1

ftdebug.c files are new, adapted the import script to copy the source
file for Windows as well.

Replaced the CMakeLists.txt content that was imported from the .pro file
with the respective variables and logic from the freetype CMakeLists.txt
file, which should make it easier to maintain this next time.

Pick-to: 6.4 6.3 6.2 5.15 5.12
Fixes: QTBUG-105032
Change-Id: I1e846167b268df4b1b0a50dcec602def1a0bdcb4

+   *
+   * There are now three debugging modes:
+   *
+   * - trace mode
+   *
+   *   Error and trace messages are sent to the log file (which can be the
+   *   standard error output).
+   *
+   * - error mode
+   *
+   *   Only error messages are generated.
+   *
+   * - release mode:
+   *
+   *   No error message is sent or generated.  The code is free from any
+   *   debugging parts.

+   * Variables used to control logging.
+   *
+   * 1. `ft_default_trace_level` stores the value of trace levels, which are
+   *    provided to FreeType using the `FT2_DEBUG` environment variable.
+   *
+   * 2. `ft_fileptr` stores the `FILE*` handle.
+   *
+   * 3. `ft_component` is a string that holds the name of `FT_COMPONENT`.
+   *
+   * 4. The flag `ft_component_flag` prints the name of `FT_COMPONENT` along
+   *    with the actual log message if set to true.
+   *
+   * 5. The flag `ft_timestamp_flag` prints time along with the actual log
+   *    message if set to ture.
+   *
+   * 6. `ft_have_newline_char` is used to differentiate between a log
+   *    message with and without a trailing newline character.
+   *
+   * 7. `ft_custom_trace_level` stores the custom trace level value, which
+   *    is provided by the user at run-time.
+   *
+   * We use `static` to avoid 'unused variable' warnings.
