build: remove --large-address-aware linker flag #18003

This flag was used when building 32-bit Windows executables, which we no-longer do, and is not accepted by the linker for any of the hosts we currently build for. i.e:

checking whether the linker accepts -Wl,--large-address-aware... no

--large-address-aware If given, the appropriate bit in the "Characteristics" field of the COFF header is set to indicate that this executable supports virtual addresses greater than 2 gigabytes. This should be used in conjunction with the /3GB or /USERVA=value megabytes switch in the "[operating systems]" section of the BOOT .INI. Otherwise, this bit has no effect. [This option is specific to PE targeted ports of the linker]

You can check that the appropriate bit in the COFF header of our 64-bit Windows binaries is still be set using dumpbin. i.e:

dumpbin /headers .\bitcoind.exe 

FILE HEADER VALUES
<snip>
26 characteristics
     Executable
     Line numbers stripped
     Application can handle large (>2GB) addresses
