Fix buffer configs for TH5 C224 SKU (#21624)

Why I did it The values in this config were found to be incorrect when testing. With fewer interfaces than the C256, the reserved buffer space is smaller and therefore the shared limit in this config must be smaller. The BUFFER_QUEUE macro was also not present, causing the defaults to be used which referenced lossless profiles. Work item tracking Microsoft ADO (number only):
