[mlir][Vector] Add a vblendps-based impl for transpose8x8 (both intrin and inline_asm)

This revision follows up on the conversation titled:

```[llvm-dev] Understanding and controlling some of the AVX shuffle emission paths```

The revision adds a vblendps-based implementation for transpose8x8 and further distinguishes between and intrinsics and an inline_asm implementation.

This results in roughly 20% fewer cycles as reported by llvm-mca:

After this revision (intrinsic version, resolves to virtually identical assembly as per the llvm-dev discussion, no vblendps instruction is emitted):
```
Iterations:        100
Instructions:      5900
Total Cycles:      2415
Total uOps:        7300

Dispatch Width:    6
uOps Per Cycle:    3.02
IPC:               2.44
Block RThroughput: 24.0

Cycles with backend pressure increase [ 89.90% ]
Throughput Bottlenecks:
  Resource Pressure       [ 89.65% ]
  - SKXPort1  [ 0.04% ]
  - SKXPort2  [ 12.42% ]
  - SKXPort3  [ 12.42% ]
  - SKXPort5  [ 89.52% ]
  Data Dependencies:      [ 37.06% ]
  - Register Dependencies [ 37.06% ]
  - Memory Dependencies   [ 0.00% ]
```

After this revision (inline_asm version, vblendps instructions are indeed emitted):
```
Iterations:        100
Instructions:      6300
Total Cycles:      2015
Total uOps:        7700

Dispatch Width:    6
uOps Per Cycle:    3.82
IPC:               3.13
Block RThroughput: 20.0

Cycles with backend pressure increase [ 83.47% ]
Throughput Bottlenecks:
  Resource Pressure       [ 83.18% ]
  - SKXPort0  [ 14.49% ]
  - SKXPort1  [ 14.54% ]
  - SKXPort2  [ 19.70% ]
  - SKXPort3  [ 19.70% ]
  - SKXPort5  [ 83.03% ]
  - SKXPort6  [ 14.49% ]

[COFF] [ARM64] Create symbols with regular intervals for relocations against temporary symbols

For relocations against temporary symbols (that don't persist in
the object file), we normally adjust them to reference the start of
the section.

For adrp relocations, the immediate offset from the referenced
symbol is stored in the opcode as the 21 bit signed immediate; this
means that the symbol referenced must be within +/- 1 MB from the
referenced symbol.

Create label symbols with regular intervals (1 MB intervals). For
relocations against temporary symbols, pick the preceding added
offset symbol and make the relocation against that instead of
against the start of the section.

This should fix the root issue behind
https://bugs.llvm.org/show_bug.cgi?id=52378.

[LLD] [COFF] Interpret the immediate in ARM64 adr/adrp relocations as signed 21 bit

This matches how MS link.exe interprets this relocation.

[AArch64] [COFF] Move jump tables back to the readonly section

This essentially reverts f5884d255e78305d41c28c6e001a460ff83981d8
(D57277).

That commit was made as a workaround since LLVM back then didn't
support cross-section relative relocations (IMAGE_REL_ARM64_REL32)
in COFF for ARM64. Support for this was implemented later,
in d5c5cf5ce8d921fc8c5e1b608c298a1ffa688d37 (D99572) and
382c505d9cfca8adaec47aea2da7bbcbc00fc05c (D102217).

The commit that moved jump tables to the function section noted
that it woud be ideal to utilize IMAGE_REL_ARM64_REL32.

[LLD] [COFF] Omit section symbols and IMAGE_SYM_CLASS_LABEL from the PE symbol table

The section symbols aren't of much practical use when looking at
a linked image. This shrinks one observed mingw style unstripped
binary by 14%.

IMAGE_SYM_CLASS_LABEL is in spirit the same as a temporary assembler
label that isn't emitted on the object file level at all.
