Based on feedback from https://edk2.groups.io/g/devel/message/50466,
CLANGPDB is the most acceptable tool chain name,
because this tool chain generates PE/COFF image with PDB debug symbol.
The following changes are made in this patch.
1. Update tool chain name from CLANG9 to CLANGPDB.
2. Update tool chain BUILDRULEFAMILY from CLANGPE to CLANGPDB.
3. Update CLANG9_BIN env name to CLANG_BIN without version info.

During a SetVariable () invocation, UpdateVariable () is called.
UpdateVariable () contains logic to determine whether a volatile or
non-volatile UEFI variable was set so the corresponding runtime
cache can be updated to reflect the change. The current logic simply
evaluates Variable->Volatile to determine which runtime cache should
be updated.
The problem is Variable->Volatile does not always reflect whether a
volatile variable is being set. Variable->Volatile is set to TRUE
only in the case a pre-existing variable is found in the volatile
variable store. Therefore, the value is FALSE when a new volatile
variable is written.
This change updates the logic to take this into account. If a new
variable is written successfully, the Attributes will accurately
reflect whether the variable is non-volatile. If a pre-existing
variable is modified, the Volatile field will reflect the type of
variable (Attributes are not reliable; e.g. 0x0 indicates deletion).
* Observable symptom: A volatile variable that was set successfully
might return EFI_NOT_FOUND when the variable should be found.
* The issue is a regression introduced to the variable services only
when the variable runtime cache is enabled by the following PCD
being set to TRUE:
gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache
* The issue was implemented in commit aab3b9b9a1 but the PCD was not
set to TRUE by default enabling the issue until commit e07b7d024a.

To be more specific, if following components or functionalities are used

XD (ExecutionDisable) feature, when turned on, allows page table
entry BIT63 set to 1 indicating the memory pointed by the page table
is disallowed to execute.
DxeIpl::CreateIdentityMappingPageTables() enables the XD when CPU
supports it.
Later DxeCore modifies the page table to set the BIT63 to protect
the stack/heap to disallow code execution in stack/heap.
UefiCpuPkg/CpuCommonFeaturesLib enables/disables the XD feature
according to PcdCpuFeaturesSetting.
When XD is disabled, GP fault is generated immediately because some
page entries have BIT63 set.
To fix this issue, this patch removes the XD feature logic from
UefiCpuPkg/CpuCommonFeaturesLib so the XD feature is only taken
care of by DxeIpl.

In order to permit the use of compilers that only implement the small
code model [which involves the use of ADRP instructions that require
4 KB segment alignment] for generating PE/COFF binaries with a small
footprint, we patch ADRP instructions into ADR instructions while doing
the ELF to PE/COFF conversion.
As it turns out, the linker may be doing the same, but for different
reasons: there is a silicon erratum #843419 for ARM Cortex-A53 which
affects ADRP instructions appearing at a certain offset in memory, and
one of the mitigations for this erratum is to patch them into ADR
instructions at link time if the symbol reference is within -/+ 1 MB.
However, the LD linker fails to update the static relocation tables, and
so we end up with an ADR instruction in the fully linked binary, but
with a relocation entry in the RELA section identifying it as an ADRP
instruction.
Since the linker has already updated the symbol reference, there is no
handling needed in GenFw for such instructions, and we can simply treat
it as an ordinary ADR. However, since it is guaranteed to be accompanied
by an add or load instruction with a LO12 relocation referencing the same
symbol, the section offset check we apply to ADR instructions is going to
take place anyway, so we can just disregard the ADR instruction entirely.
