[win][arm64ec] More fixes for building and testing Arm64EC Windows (#151409)

Browse Source 
* `tools/llvm-objcopy/MachO/update-section-object.test` was failing on
Windows since the input file (`macho_sections.s`) might be checked out
with the wrong line ending, resulting in difference in the size of
sections being checked.
* Removed the check for Windows in `AArch64Arm64ECCallLowering`: when
`llc` is run without an explicit target, the module's target triple is
unknown so this assert fires.
* Expect `llvm/test/CodeGen/Generic/allow-check.ll` to fail for Arm64EC:
Global ISel is not supported.
