Distributions want explicit control over optional parts so they can
state runtime dependencies before building. Let's restore the
functionality autotools used to provide.
Where possible, the selection is done by choosing whether to build a
particular item and the option name is build_$item. Example:
build_overlay. Where not possible, the option name is
with_$item. Example: with_valgrind.
Array options require a bump of required meson version to 0.44. Debian
stable has meson 0.37 which is already too old, stable-backports has
0.45, CI uses 0.45. Mesa's meson requirement is 0.44.1, for a
perspective.
Note, the old hack for not building docs when cross-compiling is
gone, as doc building can be explicitly controlled now.
v2: glib not optional
v3: bump meson version to 0.44

Meson builds libigt as a shared library, and executables naturally
have to find it at runtime. Using default options puts the library to
a normal search paths, but any modifications to the directory options
or a non-conventional prefix setting makes using LD_LIBRARY_PATH or
other library search means mandatory.
Add a build option 'use_rpath' (default: false) that makes meson set
up DT_RUNPATH at install time, pointing to the library with a path
relative to the executable, using $ORIGIN. That way the installed
executables find the library even when not installed to exactly the
build-time configured prefix path, a setup CI occasionally uses.
