_content/doc/go1.26: minor adjustments

Move the experimental goroutine leak detector to the end of the runtime
section so it isn't sandwiched between two non-experimental features.

For an optimization with debugging instructions, add a note to file an
issue if they are needed.

Add an additional link to simd/archsimd.

+On 64-bit platforms, the runtime now randomizes the heap base address
+at startup.
+This is a security enhancement that makes it harder for attackers to
+predict memory addresses and exploit vulnerabilities when using cgo.
+This feature may be disabled by setting
