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

acd644b build: remove --large-address-aware linker flag (fanquake)

Pull request description:

  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:

  ```bash
  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:

  ```powershell
  dumpbin /headers .\bitcoind.exe

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