- In this patch introduced the ExitBootService event to replace it.

The ESRT table is not required in UEFI firmware. In such cases, the
table may not be present in the UEFI Configuration Table. The mEsrtTable
is to check if the IsNestedFmpCapsule() function is invoked at runtime
to determine whether to use gEsrtManagementProtocolGuid or the ESRT
table from the Configuration Table. Unfortunately, the check does not
cover situations where the ESRT is not present, potentially resulting in
a kernel crash. This patch is intended to fix this issue.

When an ImageRecord is stored by ImagePropertiesRecordLib, it reports the
CodeSegmentSize as the SizeOfRawData from the image. However, the image
as loaded into memory is aligned to the SectionAlignment, so
SizeOfRawData is under the actual size in memory. This is important,
because the memory attributes table uses these image records to create
its entries and it will report that the alignment of an image is
incorrect, even though the actual image is correct.
This was discovered on ARM64, which has a 64k runtime page granularity
alignment, which is backed by a 64k section alignment for
DXE_RUNTIME_DRIVERs. The runtime code and data was correctly being
loaded into memory, however the memory attribute table was incorrectly
reporting misaligned ranges to the OS, causing attributes to be
ignored for these sections for OSes using greater than 4k pages.
This patch correctly aligns the CodeSegmentSize to the SectionAlignment
and the corresponding memory attribute table entries are now correctly
aligned and pointing to the right places in memory.

Resolves a new CodeQL error due to the value being incremented in the
loop being a narrower type than the variable it is being compared
against.
The variable is changed to a UINT32 type so it has the same width as
the type it is being compared against.
Issue explanation: In a loop condition, comparison of a value of a
narrow type with a value of a wide type may result in unexpected
behavior if the wider value is sufficiently large (or small). This
is because the narrower value may overflow. This can lead to an
infinite loop.

Currently, the ReadyToBoot event is only signaled when a formal Boot
Manager option is executed (in BmBoot.c -> EfiBootManagerBoot ()).
However, the introduction of Platform Recovery in UEFI 2.5 makes it
necessary to signal ReadyToBoot when a Platform Recovery boot loader
runs because otherwise it may lead to the execution of a boot loader
that has similar requirements to a regular one that is not launched
as a Boot Manager option.
This is especially critical to ensuring that the graphical console is
actually usable during platform recovery, as some platforms do rely on
the ConsolePrefDxe driver, which only performs console initialization
after ReadyToBoot is triggered.
This patch fixes that behavior by calling EfiSignalEventReadyToBoot ()
in EfiBootManagerProcessLoadOption () when invoking platform recovery,
which is the function that sets up the platform recovery boot process.
The expected behavior has been clarified in the UEFI 2.10 specification
to explicitly indicate this behavior is required for correct operation.
This is a rebased version of the patch originally written by Pete Batard.
