MSAL - update module for to work with msal-browser 3

[odinr]

Microsoft has rewritten the interface for MSAL 🥺

see changes for msal-browser@3, more than 2k files changed 😓

the "main" change is that after creating a PublicClientApplication, the instance need to await initialization

Proposed changes:

proposed change will not affect any end-users (consumer of the package)

change logic from JiT to initialize clients in the module.initialize

	}

other:

// TODO check if there is a better way to figure out the `request.origin`
PublicClientApplication.browserStorage = PublicClientApplication.getBrowserStorage();

see #1167

we might be able to remove some code, since the package now provide:

• getAccountByHomeId
• getAccountByLocalId
• getAccountByUsername
• getActiveAccount

this was "hacked" together with:

fusion-framework/packages/modules/msal/src/client/client.ts

Lines 60 to 66 in eb86f1e

	get account(): AccountInfo | undefined {
	const accounts = this.getAllAccounts();
	const account = accounts.find(
	(a) => (a as AccountInfo).idTokenClaims?.aud === this.clientId,
	);
	return account as AccountInfo;
	}

check if there is a feature to replace:

fusion-framework/packages/modules/msal/src/client/client.ts

Lines 68 to 75 in eb86f1e

	get hasValidClaims(): boolean {
	const idTokenClaims = this.account?.idTokenClaims;
	if (idTokenClaims) {
	const epoch = Math.ceil(Date.now() / 1000);
	return idTokenClaims.exp > epoch;
	}
	return false;
	}
