[lambdageek]

In particular this re-enables embedded PDB support on iOS and Android

The corresponding PR for main is #63365

but I'm not sure if that's necessary.

LGTM, the embedded pdb is now working on ios.

If memory serves, this stuff was disabled because in some scenarios it was inexplicably broken. So if it's legit working, then fine, seal of approval. But it really needs every viable permutation double-checked

[thaystg]

As far as I remember, what was inexplicably broken, was fixed here: mono/mono#18895

Awesome, thanks Thays

I don't understand this runtime (Build Browser wasm Release AllSubsets_Mono_WasmBuildTests) failure:

Likely caused by #62787. I thought the failures were unrelated and missed that one. I'll look into it.

@lambdageek should this go to release/6.0 as well?

@lewing I don't see a lot of motivation for it. Note that embedded PDB support for WASM was always enabled (it was already part of the ifdef).

It'll make it to release/6.0 when we merge it with the Maui branch commits.
