[OE-core] [PATCH v2] mesa: upgrade 26.0.6 -> 26.1.2

[Wang Mingyu < wangmy@fujitsu.com>]

From: Wang Mingyu <wangmy@fujitsu.com>

Import community patch to fix typed enum compilation error in
src/intel/compiler/jay/jay_ir.h. GCC < 13 does not support the
": uint8_t" enum syntax used in the new version, and the fix
explicitly casts the struct member to uint8_t to avoid layout
mismatches.

+Subject: [PATCH] src/intel/compiler/jay/jay_ir.h: do not used typed enum
+
+This is a C23 feature and not supported by gcc < 13, which
+many host distros still have (e.g. Debian 12).
+
+Upstream-Status: Inappropriate [yocto host distro requirements]
