fix: exclude HEIF/JXL from GraphicsMagick static build

GraphicsMagick auto-detects libheif/libjxl headers in the buildroot
but the API versions are often incompatible (e.g. GM 1.3.46 uses
heif_colorspace_nonvisual which was added in libheif 2.4+, while
static-php-cli builds an older version).

Disable both to prevent compile errors. These formats are not needed
for typical web image processing — JPEG, PNG, WebP, and GIF cover
the common use cases.
