SG2044Pkg/SdCard: Fix write fails and read timeout

[g11023225]

Fix the bug causing write operation failures and occasional read operation timeouts.
The modifications in the current commit are based on the following reasons：

1. All writable fields in NORMAL_INT_STAT_R(0x30) are W1C. Clearing a specific interrupt must not affect other fields.
2. Set CMD_TYPE to 0x3 when issuing Abort CMD (CMD12).
3. Poll PSTATE_REG.CMD_INHIBIT_DAT before sending ADTC commands to ensure it is 0 (0 for ready).
4. ACMD22 is an ADTC command with 4-byte data transfer. Configure blocksize and blockcount registers before sending it.
5. Update the command-sending code to support ACMD22.
6. Poll BUF_RD_ENABLE and BUF_WR_ENABLE in PSTATE_REG(0x24) to determine when data registers are accessible.
7. Set read and write timeouts to 100ms and 250ms, respectively.
8. Add Readme.md to guide SD card read/write stress testing.
