[meson] Add first regression test to FreeType

* tests/README.md: documentation explaining how to
  build and run the tests with the Meson build.

* tests/scripts/download-test-fonts.sh: Simple script
  to download test font files to the 'tests/data/'
  folder.

* meson.build, meson_options.txt, tests/meson.build:
  Add 'tests' option to enable building and running the
  test programs, disabled by default.

* tests/issue-1063/main.c: Simple regression test to
  exhibit issue 1063.

* .gitignore: Ignore the content of the tests/data/
  folder for now.

# Unit and regression tests for the FreeType library
## Quick Start
### Download test fonts
Run the `tests/scripts/download-fonts.sh` script, which will
download test fonts to the `tests/data/` directory first.
### Build the test programs
The tests are only built with the Meson build system, and
are disabled by default, enable the 'tests' option to compile
them, as in:
meson setup out -Dtests=enabled
meson compile -C out
### Run the test programs
meson test -C out
