Since commit fd562315, which updated waf to v2.1.1, Buildroot has
encountered issues building mpv, likely due to an outdated version of
the waf build system.

Starting with mpv v0.35, meson was introduced as an alternative to waf,
and in mpv v0.37, waf was completely removed.

This commit updates the mpv makefile to use meson, resolving the build
issues and simplifying future updates to newer versions of mpv.

All options previously used for Waf have been translated to the new
build system by replacing `--disable-feature` with `-Dfeature=disabled`
(and similarly for enabling features). Some features have special
handling:

- The `/usr` prefix is automatically passed to meson packages by
  default.
- The Android feature "has been removed since meson can detect if a
  machine is Android"[1].
- The `libmpv` parameter has been enabled in the makefile as `libmpv`
  must be built by default with mpv.
- Meson packages automatically set whether the library should be built
  statically using the `default_library` meson parameter.
- Meson automatically detects the presence of `libatomic` and passes the
  correct argument to the linker. However, it is possible to set the
  `stdatomic` meson parameter to specify whether `libatomic` must or
  must not be used.

Changes in v3:
- Set build-date to false instead of disable when Buildroot is built
  with repoducibility activated
- Link to v2: https://lore.kernel.org/r/20250106-fix_mpv-v2-1-85117ce7b16b@bootlin.com

Changes in v2:
- Extend commit log
- Remove --prefix=/usr as it is already handled by pkg-meson
- Modify call to libatomic to match meson way of doing things
- Link to v1: https://lore.kernel.org/r/20241221-fix_mpv-v1-1-d7ba39606571@bootlin.com
