[NFC] Remove unused argument (FuncName) for parseMIR (#106144)

While working on a MIR unittest, I noticed that parseMIR includes an
unused argument that sets a function name. This is not only redundant
but also irrelevant, as parseMIR is designed to parse entire module, not
specific functions, even though most unittests contain a single function
per module. To streamline the API, I have removed this unnecessary
argument from parseMIR. However, if this argument was originally
included to enhance readability or for any other purpose, please let me
know.
