[windows][arm64] use lld-link to build the compiler

[charles-zablit]

This patch fixes building the toolchain on ARM64 Windows while linking the Stage 0 compiler:

fatal error LNK1322: cannot avoid potential ARM hazard (Cortex-A53 MPCore processor bug #843419) in section 0x1; please consider using compiler option /Gy if it was not used

This is a similar fix as 034a158.

This is a workaround for #90100.

@swift-ci please test

Please associate this with an issue; the change itself is fine to unblock, but the underlying issue is something that we need to address in LLVM.

There is a comment referencing this issue with a FIXME: https://github.com/swiftlang/swift/pull/90101/changes#diff-c861caa2fcc08744108e542ca836b07e342f537566e8c5f7a21a0e9125331ed9R2848

Is that what you meant?

[compnerd]

Yeah; but can we link that into the commit message as well? But, the issue itself is good enough.

[compnerd]

Can we actually sink this into CMakeLists.txt and limit to swift-syntax? We should STRONGLY prefer link; its found real issues that lld has let slide.
