ArmPkg: rewrite vector table population macros
Unfortunately, Clang does not support the use of symbol references in .org
directives, and bails with the following error message when it encounters
them:
<...>:error: expected assembly-time absolute expression
.org DebugAgentVectorTable + 0x000
So replace the .org arguments with absolute values, and move the whole
vector table into a subsection with the appropriate alignment, and
starting at .org 0x0. This gives the same protection with respect to
entries that exceed 128 bytes, in a way that Clang supports as well.
