rusb2: restore speed-conditional hwfifo stride mask
FS-forced builds on the HS module are not a supported configuration, so
the 32-bit access path does not need to exist in full-speed builds:
CFG_TUSB_FIFO_HWFIFO_DATA_STRIDE returns to (2 | (TUD_OPT_HIGH_SPEED ? 4 : 0)).
Saves 28 bytes of text on FS-only parts (measured on ra4m1_ek cdc_msc);
high-speed builds keep both widths for the dual-module (FS+HS ports) case.
Build-verified: ra4m1_ek and ra6m5_ek cdc_msc.
