Revert "[LLD][ELF] Cortex-M Security Extensions (CMSE) Support"

This reverts commit c4fea3905617af89d1ad87319893e250f5b72dd6.

I am reverting this for now until I figure out how to fix
the build bot errors and warnings.

Errors:
llvm-project/lld/ELF/Arch/ARM.cpp:1300:29: error: expected primary-expression before ‘>’ token
 osec->writeHeaderTo<ELFT>(++sHdrs);

Warnings:
llvm-project/lld/ELF/Arch/ARM.cpp:1306:31: warning: left operand of comma operator has no effect [-Wunused-value]

-// The Arm Cortex-M Security Extensions (CMSE) splits a system into two parts;
-// the non-secure and secure states with the secure state inaccessible from the
-// non-secure state, apart from an area of memory in secure state called the
-// secure gateway which is accessible from non-secure state. The secure gateway
-// contains one or more entry points which must start with a landing pad
-// instruction SG. Arm recommends that the secure gateway consists only of
-// secure gateway veneers, which are made up of a SG instruction followed by a
-// branch to the destination in secure state. Full details can be found in Arm
-// v8-M Security Extensions Requirements on Development Tools.
-//
-// The CMSE model of software development requires the non-secure and secure
-// states to be developed as two separate programs. The non-secure developer is
-// provided with an import library defining symbols describing the entry points
-// in the secure gateway. No additional linker support is required for the
-// non-secure state.
-//
-// Development of the secure state requires linker support to manage the secure
-// gateway veneers. The management consists of:
-// - Creation of new secure gateway veneers based on symbol conventions.
-// - Checking the address of existing secure gateway veneers.
-// - Warning when existing secure gateway veneers removed.
-//
-// The secure gateway veneers are created in an import library, which is just an
-// ELF object with a symbol table. The import library is controlled by two
-// command line options:
-// --in-implib (specify an input import library from a previous revision of the
-// program).
-// --out-implib (specify an output import library to be created by the linker).
-//
-// The input import library is used to manage consistency of the secure entry
-// points. The output import library is for new and updated secure entry points.
-//
-// The symbol convention that identifies secure entry functions is the prefix
-// __acle_se_ for a symbol called name the linker is expected to create a secure
-// gateway veneer if symbols __acle_se_name and name have the same address.
-// After creating a secure gateway veneer the symbol name labels the secure
-// gateway veneer and the __acle_se_name labels the function definition.
-//
-// The LLD implementation:
-// - Reads an existing import library with importCmseSymbols().
-// - Determines which new secure gateway veneers to create and redirects calls
-//   within the secure state to the __acle_se_ prefixed symbol with
-//   processArmCmseSymbols().
-// - Models the SG veneers as a synthetic section.
-
-// Initialize symbols. symbols is a parallel array to the corresponding ELF
-// symbol table.
