MDEV-34388 default stack size under MSAN needs increasing

Browse Source 
Without this increase the mtr test case pre/post conditions will
fail as the stack usage has increased under MSAN with clang-20.1.

ASAN takes a 11M stack, however there was no obvious gain in MSAN
test success after 2M.

The resulting behaviour observed on smaller stack size was a
SEGV normally.

Hide the default stack size from the sysvar tests that expose
thread-stack as a variable with its default value.
