This adds support for `S_DEFRANGE_REGISTER_REL_INDIR` (as
`DefRangeRegisterRelIndirSym`).
It's to `S_REGREL32_INDIR` what `S_DEFRANGE_REGISTER_REL` is to
`S_REGREL32`. `S_REGREL32_INDIR` was added in #183172.
LLVM only generates `S_LOCAL` for variables and parameters, so we need
this record to specify a range where a variable is indirectly accessed.
I didn't find any PDB where this record is in, so I guessed the layout
based on `S_DEFRANGE_REGISTER_REL` and `S_REGREL32_INDIR`. Locally, I
updated LLVM to generate this where possible, and tested it with the VS
debugger and WinDBG. Both handled the record correctly. This PR doesn't
include the change to debug info generation yet - you can find the
current WIP in
884072fa17.
The name `OffsetInUdt` comes from DIA
([`get_offsetInUdt`](https://learn.microsoft.com/en-us/visualstudio/debugger/debug-interface-access/idiasymbol-get-offsetinudt?view=visualstudio)).
Given that this symbol also has a `offsetInParent`, I find the name a
bit confusing. When generating the record in the commit above, I used
the name `DerefOffset`. If we change it here, it should be changed in
`RegRelativeIndirSym` as well.
