build: Meson build system

Removes the existing Autotools build system and adds a new Meson one.
Also replaces the shell script test driver with a Python one, since
Meson already brings in a Python dependency.

Common operations:

- ./configure -> meson _build
- make -> ninja -C _build
- make install -> ninja -C _build install
- make check -> meson test -C _build
- make Tartan.pot-update -> ninja -C _build tartan-pot
- make update-po -> ninja -C _build tartan-update-po

To run the tests with coverage enabled and make a coverage report:

- meson _build -Db_coverage=true
- meson test -C _build
- ninja -C _build coverage-html
