BaseTools: add --apply-dynamic-relocs option for AARCH64 CLAGNDWARF
StandaloneMm is loaded failure when it built with clang-22.
This is because mMmMemoryMap is intialised incorrectly by compiler:
MmMain - 0xFF025040
[StandaloneMmMain:849] mMmMemoryMap: 0xFF21D238
[StandaloneMmMain:850] mMmMemoryMap->ForwardLink: 0xFF201000
[StandaloneMmMain:851] mMmMemoryMap->BackLink: 0xFF201000
The 0xFF20100 is loaded image address. However list_head -- mMemoryMap
doesn't initialised properly by ld-lld.
Here, ld with gcc initialised mMmMemoryMap list head properly:
// 0x12490: &mMmMemoryMap
# hexdump -Cv -s 0x12490 -n 64 StandaloneMmCore.efi
00012490 90 24 01 00 00 00 00 00 90 24 01 00 00 00 00 00 |.$.......$......|
...
However, ld-lld with clang doesn't:
// 0x1c238: &mMmMemoryMap
# hexdump -Cv -s 0x1c238 -n 64 StandaloneMmCore.efi
0001c238 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
To address this, add --apply-dynamic-relocs linker option.
After this patch, StandaloneMm is loaded preoperly and mMmMemoryMap
is intialised correctly:
ld-lld with clang with --aply-dynamic-reclos option:
// 0x1d238: &mMmMemoryMap
# hexdump -Cv -s 0x1d238 -n 64 StandaloneMmCore.efi
0001d238 38 d2 01 00 00 00 00 00 38 d2 01 00 00 00 00 00 |8.......8.......|

TcgTpmPkg: fix build failure of TpmLib with CLANGDWARF
When TpmLib is built with llvm, below error is splat:
edk2/TcgTpmPkg/Library/TpmLib/TPM/TPMCmd/tpm/src/crypt/CryptRand.c:388:12:
error: logical not is only applied to the left hand side of this comparison
[-Werror,-Wlogical-not-parentheses]
388 | if(DRBG_ENCRYPT_SETUP((BYTE*)key, DRBG_KEY_SIZE_BITS,

To build TCG TPM v2.0 reference library properly, ignore above warning.
