Michael Pratt 0ab64e2caa [release-branch.go1.24] runtime: cleanup M vgetrandom state before dropping P 
When an M is destroyed, we put its vgetrandom state back on the shared
list for another M to reuse. This list is simply a slice, so appending
to the slice may allocate. Currently this operation is performed in
mdestroy, after the P is released, meaning allocation is not allowed.

More the cleanup earlier in mdestroy when allocation is still OK.

Also add //go:nowritebarrierrec to mdestroy since it runs without a P,
which would have caught this bug.

Fixes #73144.
For #73141.
