* Patch Ghidra HEAD scan_number to use std::stoull for MSVC

Upstream GP-6608 (Ghidra 827ebe6a0) replaced the hand-rolled integer
parser in slghscan.l with std::stoul. std::stoul returns unsigned long,
which is 64 bits on LP64 (Linux/macOS) but 32 bits on MSVC (LLP64), so
any .slaspec integer literal wider than 0xFFFFFFFF throws out_of_range
and sleigh rejects the spec. This broke the Windows HEAD CI job on the
b211a07b5 bump (68000/PowerPC/Loongarch/coldfire/avr32a specs all have
64-bit immediates).

Swap to std::stoull, which returns unsigned long long (64 bits on all
platforms) and matches the uintb target in scan_number.

+Subject: [PATCH] Use std::stoull instead of std::stoul in scan_number for MSVC
+
+std::stoul returns `unsigned long`, which is 32 bits on MSVC (LLP64) but 64
+bits on POSIX LP64. scan_number assigns the result into a `uintb` (uint64_t),
+so on Windows any integer literal in a .slaspec file that exceeds 0xFFFFFFFF
+throws std::out_of_range, the catch-all returns BADINTEGER, and the sleigh
+compiler rejects the spec. Affected specs include 68000/PowerPC/Loongarch/
+coldfire/avr32a and others that use 64-bit immediates.
+
+std::stoull returns `unsigned long long` (64 bits on all platforms), matching
+the uintb target and the pre-GP-6608 behavior. This mirrors the earlier fix
+applied to AddrSpace::read in space.cc.
