6ef31c643a Set STACK_MARGIN_MAX to four times of pagesize on LoongArch64 
It fixed a test named tstack. Actually, Linux user get the stacktop is
incorrect in current. The value of stack pointer when enter the procedure
is thought as it is in the highest stack page. But if the parameters is
enough large, lager than 16k, most of arch will also fail this test.
Since the LoongArch default pagesize is 16k, it fail often because
stack-layout-randomization causes the stackpointer underflow to next page.
I had tried fixed it in rtl/linux/[arch]/si_*. But because the codes is
unworthy and hardly the parameters is enough large, just expand
STACK_MARGIN_MAX for simplicity.

7b9ed5fe46 rtl: make STACK_MARGIN a variable instead of a const. this allows adjusting margin size on system unit init, based on the actual stack length of the executable. useful for small systems running with little stack. allow overwriting SysBackTraceStr with a platform-specific implementation

2e2f2eb784 - remove could which prevented that rte is triggered even if we are inside 
an exception block but *without* using sysutils. The remove code
    was once added to have primitive exception handling even if
    no sysutils is used. But if this is desired, an appropriate handler
    to ErrorProc should be assigned. Resolves #38201

8d95da3fea * Windows: Reworked handling of command line arguments to properly support Unicode: 
- Use the CommandLineToArgvW API function to parse the Unicode command line (we can use it since Win9x is not supported anymore).
  - Implemented non-public functions ParamStrA and ParamStrU which are exposed in the objpas and uuchar units to provide correct AnsiString and UnicodeString versions of ParamStr(). 
  - The cleanup code is moved from InternalExit to the finalization section of the System unit.
