Fix T91444: Edge Loop Preview fails with two Mirror Modifiers

The mirror modifiers merge option caused unnecessary re-ordering
to the vertex array with original vertices merging into their copies.

While this wasn't an error, it meant creating a 1:1 mapping from input
vertices to their final output wasn't reliable (when looping over
vertices first to last) as is done in
BKE_editmesh_vert_coords_when_deformed.

As merging in either direction is supported, keep the source meshes
vertices in-order since it allows the vertex coordinates to be extracted.

NOTE: Since this change introduce issues for some cases (e.g. bound
modifiers like SurfaceDeform), this change is only applied to newly
created modifiers, existing ones will still use the old incorrect merge
behavior.

UI: Fix alignment for recently added/edited icons

The patch slightly modifies two recently added icons "FILE_BLEND" and
"CURRENT_FILE" to better align them to the pixel grid, and change the
design of "FILE_BACKUP" to avoid alignment and readability issues, as
well as avoiding the outline version of the Blender logo which violates
the official logo guidelines.

Fix T93244: Cycles HIP not working with multi GPU rendering

Fix T92090: Eevee crash with Intel HD 4000 and macOS 10.15.7

A recent security update to macOS 10.15.7 causes crashes when using Eevee and
various other 3D viewport features. It appears that glGenerateMipmap is
broken, causing a crash whenever its commands are flushed/submitted to the GPU.

Ideally this would be fixed in a driver update, however it's unlikely this will
happen. Earlier macOS versions have been receiving security updates for 2 years,
and that window has just passed for 10.15. Further, computers with these GPUs
can't upgrade to a newer macOS version.

As a workaround, disable mipmaps on these GPUs, by setting the mipmap max level
to 0 and not calling glGenerateMipmaps. Effects like depth of field also use
mipmaps, but fill in the mip levels by other means. In those cases we keep the
mipmap level.

Fix T85855: F-curves too thin on Mac

Use the `GPU_SHADER_3D_POLYLINE_UNIFORM_COLOR` shader instead of `GPU_SHADER_2D_LINE_DASHED_UNIFORM_COLOR`.
This is just a partial solution as "protected" fcurves still use the dashed shader.
