[llvm-readobj] Remove --raw-relr

https://reviews.llvm.org/D47919 dumped RELR relocations as
`R_*_RELATIVE` and added --raw-relr (not in GNU) for testing purposes
(more readable than `llvm-readelf -x .relr.dyn`). The option is obsolete
after `llvm-readelf -r` output gets improved (#89162).

Since --raw-relr never seems to get more adoption. Let's remove it to
avoid some complexity.

[SHT_LLVM_BB_ADDR_MAP] Adds pretty printing of BFI and BPI for PGO Analysis Map in tools. (#82292)

Primary change is to add a flag `--pretty-pgo-analysis-map` to
llvm-readobj and llvm-objdump that prints block frequencies and branch
probabilities in the same manner as BFI and BPI respectively. This can
be helpful if you are manually inspecting the outputs from the tools.

In order to print, I moved the `printBlockFreqImpl` function from
Analysis to Support and renamed it to `printRelativeBlockFreq`.

[llvm-readobj] Switch command line parsing from llvm::cl to OptTable

Users should generally observe no difference as long as they don't use
unintended option forms. Behavior changes:

* `-t=d` is removed. Use `-t d` instead.
* `--demangle=false` and `--demangle=0` cannot be used. Omit the option or use `--no-demangle`. Other flag-style options don't have `--no-` forms.
* `--help-list` is removed. This is a `cl::` specific option.
* llvm-readobj now supports grouped short options as well.
* `--color` is removed. This is generally not useful (only apply to errors/warnings) but was inherited from Support.

Some adjustment to the canonical forms
(usually from GNU readelf; currently llvm-readobj has too many redundant aliases):

* --dyn-syms is canonical. --dyn-symbols is a hidden alias
* --file-header is canonical. --file-headers is a hidden alias
* --histogram is canonical. --elf-hash-histogram is a hidden alias
* --relocs is canonical. --relocations is a hidden alias
* --section-groups is canonical. --elf-section-groups is a hidden alias

OptTable avoids global option collision if we decide to support multiplexing for binary utilities.

* Most one-dash long options are still supported. `-dt, -sd, -st, -sr` are dropped due to their conflict with grouped short options.
* `--section-mapping=false` (D57365) is strange but is kept for now.
* Many `cl::opt` variables were unnecessarily external. I added `static` whenever appropriate.

[llvm-readobj] Make -s and -t match llvm-readelf

llvm-readobj is an internal testing tool for binary formats. Its output and
command line options do not need to be stable. It isn't supposed to be part of a
build process.

llvm-readelf was created as a user-facing utility and its interface intends to
be compatible with GNU readelf (unless there are good reasons not to).

The two tools have mostly compatible options. -s and -t are noticeable
exceptions due to history. I think the cost of keeping the inconsistency
overweighs the little history-compatible benefit and hinders transition from
cl::opt to OptTable, so let's change it.
