Metal: Use a quad for blit with draw

Adjusted blit emulation to use a two-triangle quad
instead of an implicitly clipped triangle to avoid
interpolation artifacts on Apple silicon.

Reduced the BlitParams struct size from 48 to 32 bytes.

Disabled perspective correction as it has no effect anyway.

Fixed the following tests on Apple silicon:

    dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_mag
    dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_mag_reverse_src_x
    dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_mag_reverse_src_y
    dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_mag_reverse_dst_x
    dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_mag_reverse_dst_y
    dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_mag_reverse_src_dst_x
    dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_mag_reverse_src_dst_y
    dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_min_reverse_src_y
    dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_min_reverse_dst_y
