The BaseTools build feature introduced for TianoCore#1804 / in commit
1fa6699e6c ("BaseTools: Add a checking for Sources section in INF file",
2019-06-10) logs some (non-fatal) warnings about unlisted internal header
files. List those files explicitly.
Note: header files are added in lexicographical order only if the
underlying INF file already keeps the [Sources] and [LibraryClasses]
sections in lexicographical order. Otherwise, header files are added in
rough "logical" order.

DEBUG builds of PEI code will print a diagnostic message regarding
the utilization of temporary RAM before switching to permanent RAM.
For example,
Total temporary memory: 16352 bytes.
temporary memory stack ever used: 4820 bytes.
temporary memory heap used for HobList: 4720 bytes.
Tracking stack utilization like this requires the stack to be seeded
with a known magic value, and this needs to occur before entering C
code, given that it uses the stack. Currently, only Nt32Pkg appears
to implement this feature, but it is useful nonetheless, so let's
wire it up for PrePeiCore.

The PrePeiCore vector table for AArch64 mode is only half populated.
However unlikely, if exceptions from lower exception levels are ever
taken, they should be reported correctly, rather than causing a

We currently rely on .align directives to ensure that each exception
vector entry is the appropriate offset from the vector base address.
This is slightly fragile, as were an entry to become too large (greater
than 32 A64 instructions), all following entries would be silently
shifted until they meet the next alignment boundary. Thus we might
execute the wrong code in response to an exception.
To prevent this, introduce a new macro, VECTOR_ENTRY, that uses .org
directives to position each entry at the precise required offset from
the base of a vector. A vector entry which is too large will trigger a
build failure rather than a runtime failure which is difficult to debug.
For consistency, the base and end of each vector is similarly annotated,
with VECTOR_BASE and VECTOR_END, which provide the necessary alignment
and symbol exports. The now redundant directives and labels are removed.

Since PrePeiCore's .text section contains an AARCH64 exception
vector table, its 2 KB alignment propagates to other sections as
well. Since this is a SEC module, it should not have any writable
data in the first place, so change some non-const PPI globals to
const. The resulting binary has no .data section at all, which
saves 2 KB in the XIP image.
