Implement Solana support for "The Wallet Standard"

Implement Solana support for "The Wallet Standard" https://github.com/wallet-standard/wallet-standard support in brave-core

jsx
Hi Brave team 🙂 The Wallet Standard (https://github.com/wallet-standard/wallet-standard) reached 1.0.0 before Breakpoint, and has been stable since. It’s used by many major Solana dapps now (see anza-xyz/wallet-adapter#604 for an incomplete list). There’s an integration guide for wallets (https://github.com/solana-labs/wallet-standard/blob/master/WALLET.md). Since Brave already presents a Phantom-compatible interface, this should be very simple to add. It’s a nonbreaking change (your current interfaces will continue to work exactly as is) and adds no external runtime dependencies. If you integrate this, Brave will show up in the top of the wallet adapter list for all these applications and more. You won’t have to overwrite window.solana or conflict with other wallets. Please let me know if I can help support you!

The above requires 1.47.178 or higher for 1.47.x verification 👍

We'll need to recheck this once @darkdh lands a fix that resolves the performance issues mentioned via #27997. @darkdh can you let is know once the performance issues are fixed and the above can be verified? We'll probably uplift the above into 1.47.x as well with the fix.

[kjozwiak]

Moving this into 1.48.x as we neve received another C109 minor chromium bump that would have triggered another 1.47.x release. We'll leave https://github.com/brave/brave-core/milestone/267 as there's code that landed in 1.47.x but we'll close off the 1.47.x - Release #6 milestone and move all the issues within 1.48.x. The above can be verified with 1.48.156 for 1.48.x.

[kjozwiak]

@srirambv we'll need to re-run through the above now that #27997 was fixed/merged. Originally it was planned to go out via 1.47.x but looks like we never received a 1.47.x as per #27340 (comment).

I labelled #27997 (comment) as QA/No but if you're running through the above and have some time, can run through the cases that @darkdh mentioned via brave/brave-core#16868 (comment).
