firefox-fourier: flatten patches to top-level (makepkg has no subdir support)

Follow-up to #10. The subdir layout I assumed worked turned out to not work — per 'man PKGBUILD': The filename in the array must NOT include any path components like ./ makepkg's source-staging only honors basenames; the patches/ subdir references staged the files but the basename-lookup at apply time failed with the same 'not found in build directory' error that #9 hit. I copied the chromium-fourier convention thinking it was proven, but chromium-fourier has no CI either and likely has the same latent breakage (separate issue, not in this PR's scope). The actually-working pattern is the mpv-fourier one: patches at the top level next to the PKGBUILD. mpv-fourier iter2 just built green on CI (#92) with that layout. This commit: - Moves all 8 patches (5 fourier + 3 arch upstream) from patches/ to arch/firefox-fourier/ via git mv (preserves blame). - Removes the now-empty patches/ subdir. - Strips 'patches/' prefix from source array entries. - Strips '/patches' from prepare() patch -i paths. No semantic change to the patch content or apply order. pkgrel 3 -> 4.

+Subject: [PATCH 1/4] widget/gtk: recognize V4L2 stateless fourccs in
+ GfxInfo prober (S264 / S265 / VP9F)
+Date: 2026-04-27
+
+Background
+----------
+Firefox's V4L2 prober in `widget/gtk/GfxInfo.cpp::V4L2ProbeDevice`
+parses `v4l2test`'s `V4L2_OUTPUT_FMTS` line and matches against the
+fourccs of stateful V4L2-M2M decoders (`H264`, `VP80`, `VP90`, `HEVC`).
+That's correct for Pi4 / Mediatek / vendor-MPP stateful decoders but
+silently skips every mainline-Linux Rockchip board: RK3399 `rkvdec`,
+RK3566 `hantro` (multiplanar), RK3588 `hantro` and `rkvdec2` all
+expose stateless fourccs only — `S264`, `S265`, `VP9F`. The probe
+binary itself enumerates these correctly (verified end-to-end on
+fresnel / Pinebook Pro / RK3399 with `v4l2test --device /dev/video1`
+showing `V4L2_OUTPUT_FMTS:  S265 S264 VP9F` and
+`V4L2_SUPPORTED: TRUE`); the gap is purely in this string table.
+
+This patch adds the three sibling blocks for the stateless fourccs,
+each identical in shape to the existing stateful blocks except for
+setting a new `mV4L2IsStateless` member. The follow-up patches in
+this series (2/4, 3/4, 4/4) consume that member to route through the
+libavcodec v4l2_request hwaccel (`AV_HWDEVICE_TYPE_DRM`) instead of
+the v4l2m2m codec wrapper used for stateful boards.
+
+Bug 1969297.
