OvmfPkg: set 4 KB section alignment for DXE_RUNTIME_DRIVER modules
Increase the section alignment to 4 KB for DXE_RUNTIME_DRIVER modules.
This allows the OS to map them with tightened permissions (i.e., R-X for
.text and RW- for .data). This is a prerequisite for enabling the
EFI_PROPERTIES_RUNTIME_MEMORY_PROTECTION_NON_EXECUTABLE_PE_DATA (sic)
feature that was introduced in UEFIv2.5.
