ArmPkg: convert LFs to CRLF, expand hard TABs

ArmPkg: convert LFs to CRLF, expand hard TABs

We're going to switch the internal line terminators globally to LF at some
point, but until then, let's use CRLF consistently. Convert source files
with LFs in them to CRLF, using "unix2dos".

"git show -b" prints no code changes for this patch.

(I collected all the file name suffixes in this package, with:

$ git ls-files -- $PACKAGE | rev | cut -f 1 -d . | sort -u | rev

I eliminated those suffixes that didn't stand for text files, then
blanket-converted the rest with unix2dos. Finally, picked up the actual
changes with git-add.)

At the same time, the following three files had to undergo TAB expansion:

  ArmPkg/Library/ArmSoftFloatLib/ArmSoftFloatLib.c
  ArmPkg/Library/GccLto/liblto-aarch64.s
  ArmPkg/Library/GccLto/liblto-arm.s

I used "expand -t 2", in order to stay close to the edk2 coding style
(which uses two spaces for indentation.)

Both the CRLF conversion and the TAB expansion are motivated by
"PatchCheck.py". "PatchCheck.py" is also the reason why CRLF conversion
and TAB expansion have to happen in the same patch.
