RFR: 8371948: TestStackOverflowDuringInit.java fails xss too small on linux-aarch64 [v3]

[SendaoYan]

> Hi all,
> 
> On linux-aarch64, when page size is 64K, the minimal java thread stack size is 448K. So this PR increase the minimal java thread stack size in test/hotspot/jtreg/runtime/ClassInitErrors/TestStackOverflowDuringInit.java. Below is the calculation formula for the minimal java thread stack size:
> 
> 
> page_size = 64K
> _java_thread_min_stack_allowed = 72K
> _stack_red_zone_size = align_up(StackRedPages * unit, page_size) = align_up(1*4K, 64K) = 64K
> _stack_yellow_zone_size = align_up(StackYellowPages * unit, page_size) = align_up(2*4K, 64K) = 64K
> _stack_reserved_zone_size = align_up(StackReservedPages * unit, page_size) = align_up(1*4K, 64K) = 64K
> _stack_shadow_zone_size = align_up(StackShadowPages * unit, page_size) = align_up(25*4K, 64K) = 128K
> _java_thread_min_stack_allowed = align_up(72K+64K+64K+64K+128K, 64K) = 448K
> 
> 
> This PR add whitebox API getMinimumJavaStackSize() to the the allowd minimum java stack size, and get the allowed minimum java stack size in test/hotspot/jtreg/runtime/ClassInitErrors/TestStackOverflowDuringInit.java
> 
> Change has been verified locally both on linux-x64 and linux-aarch64.
