Daniel Black f2ef683b7a MDEV-37705 main.lotofstack /main.sp-error fails in MSAN+Debug
Tests on clang-20/21 had both of these tests overrunning the
stack. The check_stack_overrun function checked the function
earlier with a 2*STACK_MIN_SIZE margin. The exection within
the processing is deeper then when check_stack_overrun was
called.

Raising STACK_MIN_SIZE to 44k was sufficient (and 40k wasn't
oufficient). execution_constants also tested however
the topic mention tests are bigger.

Perfscheam tests
* perfschema.statement_program_nesting_event_check
* perfschema.statement_program_nested
* perfschema.max_program_zero

A small increase to the test thread-stack-size on statement_program_lost_inst
allows this test to continue to pass.
