[dsymutil][llvm-dwarfutil] Rename command line options to avoid using vendor names. (#78135)

This patch renames values of dsymutil/llvm-dwarfutil options:

--linker apple -> --linker classic
--linker llvm -> --linker parallel

The purpose to rename options is to avoid using vendor names and to
match with library names. It should be safe to rename options at current
stage as they are not seemed widely used(we may not preserve backward
compatibility).

1. Types deduplication(--odr mode).
2. Modules deduplication.
3. Generation of index tables.

Reland2: temporarily disabled call to "--linker llvm" for tls-variable.test
and location-expression.test as it does not work properly on bigendian
architecture.

[Reland][DebugInfo][llvm-dwarfutil] Combine overlapped address ranges.

DWARF files may contain overlapping address ranges. f.e. it can happen if the two
copies of the function have identical instruction sequences and they end up sharing.
That looks incorrect from the point of view of DWARF spec. Current implementation
of DWARFLinker does not combine overlapped address ranges. It would be good if such
ranges would be handled in some useful way. Thus, this patch allows DWARFLinker
to combine overlapped ranges in a single one.

Depends on D86539
