[llvm-strip] Support -s alias for --strip-all. Make both strip and objcopy case sensitive to support both -s (--strip-all) and -S (--strip-debug).
Summary:
GNU strip supports both `-s` and `-S` as aliases for `--strip-all` and `--strip-debug`, respectfully.
As part of this, it turns out that strip/objcopy were accepting case insensitive command line args. I'm not sure if there was an explicit reason for this. The only others uses of this are llvm-cvtres/llvm-mt/llvm-lib, which are all tools specific for windows support. Forcing case sensitivity allows both aliases to exist, but seems like a good idea anyway.
And as a surprise test case adjustment, the llvm-strip unit test was running with `-keep=unavailable_symbol`, despite `keep` not be a valid flag for strip. This is because there is a flag `-K` which, when case insensitivity is permitted, allows it to be interpreted as `-K` = `eep=unavailable_symbol` (e.g. to allow `-Kfoo` == `--keep-symbol=foo`).
