Introduce new attribute classes:
* addrptr represents an offset into the .debug_addr_section
* loclist represents an offset or an index to a location list
* rangelist represents an offset or an index to a range list
* stroffsetsptr represents an index to the indirect string table
The semantics of some existing attribute classes changed:
* loclistptr represents an offset into the
.debug_loc / .debug_loclist section
It will be used only when setting loclists_base attribute.
In all other places we should use loclist attribute class.
* rangelistptr represents an offset into the
.debug_ranges / .debug_rnglist section
It will be used only when setting rnglists_base attribute.
In all other places we should use rangelist attribute class.
Define lookup table for new DW_AT_* attribute types
* change the existing references to AC_LOCLISTPTR to AC_LOCLIST
as in those places now either an index or an offset can be accepted
(previously there were no indexes, only offsets everywhere)
* only DW_AT_loclists_base uses AC_LOCLISTPTR
* similarly for AC_RANGELISTPTR and AC_RANGELIST as ranges
can be specified using either an index or an offset
* only DW_AT_rnglists_base uses AC_RANGELISTPTR
Define lookup table for new DW_FORM_* attribute forms
* similar reshuffle for location lists and range lists

the relocated value is symbol_value + addend. see e.g. in uclibc:

Differences between DWARF v3/v4 for line-info:
- added new field maxOpsPerInstruction
this new field will typically have the value of 1
unless VLIW architecture is being used
(which is not the case for Haiku)
- state machine contains a new field op_index
it has any relevance only when maxOpsPerInstruction > 1
i.e. on VLIW architectures
- added new operation DW_LNE_set_discriminator
this is already implemented in LineNumberProgram.cpp
This implementation just reads maxOpsPerInstruction and
checks that it is set to 1, which is what we expect on
all architectures currently supported by Haiku.

* Reuse TEX[2] for SWDBM flag which should be availble

* Introduce SetAndClearPageTableEntryFlags for updating

* Startup sequence is handled similarly to accessed flag, i.e.
set Modified flag in initially mapped pages in bootloader and early map.
* Once the kernel initialization has progressed enough,
pages are mapped as read-only and modified flag handling is done
in the page fault handler.

- memory type 0 is Strongly-Ordered
- memory type 1 is Shareable Device
- memory type 2 is Normal, Inner/Outer Write-Through
- memory type 3 is Normal, Inner/Outer Write-Back, no Write-Allocate
This way no change is needed in B and C bits so we can keep the
existing MemoryTypeToPageTableEntryFlags() implementation.

Pages should not be marked as accessed when initially mapping them.
However, there's a short interval during kernel startup when new pages
are mapped but the fault handler is not installed yet.
Therefore, we set Accessed Flag to 1 in early_map.
Once the kernel initialization has progressed enough, we start mapping
new pages with Accessed Flag set to 0.
The chicken and egg problem of initially mapping the vector page is
tackled by preallocating the vector page in the boot loader.

This change moves the common functions related to EFI memory map
to arch/generic for arm, arm64, x86.
riscv64 and x86_64 shall be handled separately as they use some
more architecture-specific logic:
* riscv64 needs special treatment for the M-mode resident code
located at 0x80000000 which is reported as available in the
EFI memory map provided by u-boot.
* x86_64 has a slightly different logic for building the
memory regions list so some additional rework and testing will be
needed before it can be unified with the generic mmu functions.
