Allow hyperlight_guest_bin to compile with windows target.

[ludfjig]

.type x,@function-style directives are unsupported on windows toolchain and assembler. As far as I know, removing these should not affect functionality.

Patch similar to this one has been done before 42ee008, but was not applied when setjmp was brought back in #499

This was never caught before because hyperlight_guest_bin is never used with a windows toolchain. I only noticed it because rust-analyzer complains when I use my windows machine, which is annoying.

Why do we need this to compile as a windows target, we don't compile for windows guests any longer, can we make a fix that causes the correct target to be used by the analyzer on Windows

[simongdavies]

I dont think this is the right way to do this, we need to either figure out how to get the analyzer to build with the correct target/settings and/or exclude this member from the workspace like we did with the test binaries

I just updated #572 so that running cargo build in the root directory of hyperlight_guest_bin works on windows by adding a cargo.toml file
