[PATCH v1 1/1] StandaloneMmPkg: To support CLANGPDB build

["Jiyang Yang" <jiyangx.yang@intel.com>]

the flag "-fpie" is passed for all builds with a GCC family toolchain,
including CLANGPDB, but CLANGPDB does not support this flag, it will
report "clang: error: unsupported option '-fpie' for target
'x86_64-unknown-windows-gnu'". So we add the CLANGPDB option "-fno-pie"
later to overwrite it.
