Roy Ivy III c015f15d8d make.bat: fix use of make.bat from v up (#16348)
* .editorconfig: fix EOL for BAT files

* make.bat: fix use of `make.bat` from `v up`

- use move semantics, instead of replace, for `v` executable updates
- fixes [#16184](https://github.com/vlang/v/issues/16184)

# [why]

`v up` updates the executable by directly calling `make.bat`, awaiting
the result, which keeps an open file handle to it's own executable file.
`make.bat` compiles and, crucially, attempts to directly replace that
`v` executable. But, in WinOS, files with open file handles cannot be
deleted/replaced, so the `make` then fails. The other key point is that,
although WinOS files with open file handles can't be deleted/replaced,
they _can be moved/renamed_.

Thus, the technique that most self-updating WinOS executables use is to
move the current executable to some alternate name (ie, *v_old.exe*) and
then move the newly updated executable to the original location (ie,
*v.exe*). The next invocation of the "original" executable will then run
the updated version.

Note, this technique also works correctly for direct invocations of `make.bat`.
