[meson] Change Zlib configuration option.
* meson_options.txt, meson.build: Change the format of the 'zlib' meson build configuration option to be a combo with the following choices: - none: Do not support gzip-compressed streams at all. - internal: Support gzip-compressed streams using the copy of the gzip sources under `src/gzip/`; this should only be used during development to ensure these work properly. - external: Support gzip-compressed streams using the 'zlib' Meson subproject, linked as a static library. - system: Support gzip-compressed streams using a system-installed version of zlib. - auto: Support gzip-compressed streams using a system-installed version of zlib, if available, or using the 'zlib' subproject otherwise. This is the default. - disabled: Backward-compatible alias for 'none'. - enabled: Backward-compatible alias for 'auto'.
