Revert "update Skia to chrome/m91" (tdf#141680)

The m91 snapshot seems to cause a number of Vulkan problems.
My commit already worked around one, but there are apparently
others, such as very slow startup, or a failed Skia assertion
triggered by VCL Skia's copyArea().

This reverts commit 09d850e46903a528d4b08d3fdf03c3964d79fbc5.
